2017-2018 Annual Report Singh Center for Nanotechnology

A Message from the Director As we celebrate our fifth year of operations at the Singh Center for Nanotechnology, I am pleased with our continued transformation from a select group of independent research laboratories to a cutting-edge multipurpose nanotechnology facility that serves the community needs of academic, industrial and entrepreneurial users in the Mid-Atlantic region. Guided by our mission in being a catalytic force for research and innovation, our Center has shown robust advancement and growth in all areas of operations, most notably in the efforts to provide training and educational opportunities to our internal users and external community. Our user numbers have diversified for the fourth consecutive year, and itâ&#x20AC;&#x2122;s worthwhile to note, our customers have substantially increased geographically; users came from 33 states, up from 19 in 2017 and 13 in 2016. We attribute a portion of this increase to the programs and training our Center provides, and the tremendous support of the National Science Foundationâ&#x20AC;&#x2122;s (NSF) National Nanotechnology Coordinated Infrastructure (NNCI) program, a coalition comprised of 16 university research and development facilities dedicated to nanoscale research throughout the United States. With this increase, our Center has sought to bolster our strategic planning with the establishment of an external advisory board. The role of this board, a group of accomplished industry and academic professionals with experience in global business and technology, is to provide guidance and assistance with the needs and strategic goals of the Center. Their collective experience and insight should prove resourceful in our managerial decision-making efforts. As part of the NNCI network, the Singh Center for Nanotechnology participated in several consortium activities throughout the year, including hosting the October 2017 NNCI Meeting where 80 representatives of the 16 nodes were in attendance. Additional cooperative NNCIrelated activities include leading efforts to negotiate the purchase price of network-wide nanolab materials and consumables. At the core of our mission is the equipment that we provide to our users. Our goal is to ensure the Centerâ&#x20AC;&#x2122;s tools and equipment meets the needs of our most advanced researchers. We have made a substantial financial investment in the acquisition of two transmission electron microscopes (TEMs) to complement our suite of next-generation tools. One of these microscopes is the first of its kind installed in North America, and allows researchers to study materials at the atomic level with unprecedented precision.

In addition to fulfilling our research mandate, our commitment to provide resources to the regional community has taken considerable investment in two key areas of support: education and outreach. From an educational perspective, the University, in understanding the global impact of nanoscience, has established nanotechnology courses. These courses offer academic instruction on nanotechnology, and provide hands-on instruction in device making and fabrication. Every year the Center's Research for Undergraduate Experience (REU) Program provides research opportunities to undergraduates from outside colleges and universities. The ten-week program assigns research projects to students along with Penn faculty mentors to offer academic guidance to develop broader scientific and career skills. Within the last three years, our Seed Grant program has offered close to $50,000 in lab fees, equipment, and technical support to more than 25 startup companies and individuals engaging in early stage product development. Continuing this trend on the academic front, the Center has created several training programs to provide students with hands-on instructions in cleanroom techniques and building nanofabrication devices. The Graduate Student Fellows program (GSF), offers in-the-lab training on device creation and tool maintenance, and provides masters students with additional skills beyond classroom instruction. The Center continues to support year-round initiatives in nanotechnology outreach education, including STEM-focused events such as NanoDay. The Center also provides boot camps and training courses to the community at large every semester on nanoscience topics. As weâ&#x20AC;&#x2122;ve surpassed our projections during this five-year mark, our focus is intensely concentrated on the future to ensure this bedrock of success provides a solid foundation to build upon for the approaching years. Through strategic planning and engagement with the School of Engineering and Applied Science, and support from the University of Pennsylvania, weâ&#x20AC;&#x2122;re confident of our vision and path for the future. Our success wouldnâ&#x20AC;&#x2122;t have been achieved without the support of our family of staff, faculty and advisors of the Center. For their commitment, I commend their efforts through these first five years, and I welcome their engagement in challenges and endeavors in the approaching years. Sincerely, Mark G. Allen

Facilities Highlights EQUIPMENT ACQUISITION The Singh Center for Nanotechnology capital investments totaled $5.4M in equipment purchases for 2017-2018. Most prominent among the acquisitions are the JEOL NEOARM, and the JEOL F200 microscopes. The JEOL NEOARM is the first instrument of its kind installed in North America and is essential for research projects that require the highest levels of magnification. Additional purchases include four process furnace tubes, as well as enhancements to our scanning probe facility, and some additional smaller support pieces of fabrication equipment.

2015-16 Annual Report 2017-2018 SinghEquipment New Center for Nanotechnology

Microscopes JEOL NEOARM and JEOL F200 The JEOL NEOARM is a scanning / transmission electron microscope, equipped with a spherical aberration corrector for the probe-forming optics. This corrector has improved stability and optimizes 5th order aberrations, leading to <0.7Ă&#x2026; imaging at 200kV, and <1.6Ă&#x2026; at 30kV. The instrument is equipped with a high-brightness cold field emission source, and two large area energy dispersive x-ray spectrometers that permit rapid atomic-resolution EDS mapping. It is also equipped with a Gatan Image Filter, incorporating Dual EELS capability to ensure accurate energy calibration, and a K2-IS direct electron detector at the end of the filter. This detector has a detection quantum efficiency that is close to 1.0, and thus allows high sensitivity, leading to the detection of very high energy losses. The detector also allows 2k x 2k image acquisitions at 400 frames/second, and 512k x 512k image acquisitions at 1600 frames/second, making it optimal for in-situ/ operando microscopy. The instrument will have STEMx capability, which allows rapid collection of diffraction images during STEM acquisition, and which thus allows ptychography (a technique to overcome diffractionpattern phase problems), strain measurement, and other novel forms of quantitative image information extraction. The JEOL F200 is is a 200kV scanning / transmission electron microscope with a cold field emission source, two large area energy dispersive x-ray spectrometers, and Gatan OneView IS camera for in situ/operando imaging at 30 frames per second. Like the JEOL NEOARM, the F200 will also incorporate STEMx capability.

The JEOL NEOARM transmission electron microscope is the first to be installed in the United States.

Scanning Probe Lab Enhancements Raman-NSOM System A third laser (491 nm) for the Raman-NSOM system to complement the wavelengths of the existing lasers has been added. The 491 nm laser provides higher spatial resolution and improved Raman yield for a given amount of laser power when compared with the other lasers and is better suited to analyze surface-enhanced Raman modes. Disco TIRF The Disco TIRF is a special implementation of Total Internal Reflection Fluorescence microscopy that introduces a pivoting mirror to rotate the source of laser illumination. By rotating the laser beam 360 degrees azimuthally (at about 30 Hz) we in effect replace a point source with a ring source, yielding a more even excitation and sharper fluorescence images.

Process Hood for Furnace Operations To accompany the new furnaces the Quattrone Nanofabrication Facility installed a new wet bench from ReynoldsTech to handle the RCA clean steps to prepare samples for processing in the new MRL Cyclone furnaces. The wet bench is equipped with two heated quartz tanks, an unheated tank for dilute HF, and three dump-rinse tanks to ensure the cleanliness of samples prior to processing in the furnaces. Probe Station The Quattrone Nanofabrication Facility has acquired and installed a manual probe station from Micromanipulator, capable of accommodating samples up to 200 mm wafers, with five individual probes available, and separate chuck biasing. It is currently supported with two Keithley model 2450 Source/Meter units which are capable of sourcing/measuring 20 mV to 200 V, 10 nA to 1 A, with an output power of 20 Watt.

Quattrone Nanofabrication Facility Additions Furnaces The Local and Scanning Probe facility recently installed a 4-stack MRL Cyclone furnace from Sandvik Thermal Process Inc. equipped with: • An atmospheric wet/dry thermal oxidation tube • An LPCVD tube for deposition of silicon nitride and HTO, • Two atmospheric anneal tubes plumbed with Nitrogen and a 5% hydrogen/95% nitrogen mix for annealing RCA cleaned, and non-RCA cleaned samples. The system is designed to accommodate sample sizes ranging from pieces to full 150 mm wafers and up to a load of 50 wafers.

The study of the transformation of minerals down to the nano- and near-atomic scale allows for exploration of their geological history and the effects of environmental exposure (e.g., weathering). Analogously, transformations occurring at this scale can be used to improve our knowledge of the mechanisms and lead to understanding mineral-related health effects and comprehend how to “disarm” these minerals through bioremediation strategies. The combination of ESEM and advanced TEM techniques give a complete picture of the state of minerals starting from their crystallo-chemical identity and morphology down to the oxidation state and binding of its atoms. Ruggero Vigliaturo’s group from Penn’s Earth and Environmental Science department conducted this research.

Researchers from the Penn schools of Medicine and Engineering and Applied Science studied the diffusion of quantum dots (QDs) within cells to gain a better understanding of a drug delivery mechanism. The QDs were injected into individual cells with a nano-pipette and then tracked via fluorescence microscopy at the Local and Scanning Probe facility. Particle tracking illustrated in the figure below, revealed significant enhancement in the mobility of biocompatible quantum dots, within fibrosarcoma cells versus their healthy counterparts, fibroblasts, as well as in actin destabilized fibroblasts versus untreated fibroblasts, demonstrating that intracellular diffusion of non-specific nanoparticles is enhanced by disrupting the actin network, which has implications for drug delivery efficacy. This work has been recently published in Soft Matter, 2017, 13, 1873-1880, “Intracellular nanoparticle dynamics affected by cytoskeletal integrity”, Martha E. Grady, Emmabeth Parrish, Matthew A. Caporizzo, Sarah C. Seeger, Russell J. Composto, and David M. Eckmann.

Academic and Industry Collaboration: Microfluidics Devices for Pharmaceuticals Pharmaceuticals owe their effects not only to their chemical composition, but also to their packaging of these drugs into specific physical formulations. Many drugs are encapsulated in solid microparticles, whose size and shape determine the timing of the drugâ&#x20AC;&#x2122;s release. Consistency is a key parameter and standard manufacturing techniques may produce uneven results. Microfluidics provides a potential solution to these problems. However, there are intrinsic limitations to how fast these microscale devices can work. A team at Penn, in collaboration with researchers at the pharmaceutical company GlaxoSmithKline, has created a new architecture that can manufacture these drug particles a thousand times faster than ever before. These systems, built in our centerâ&#x20AC;&#x2122;s microfluidics lab, contain more than 10,000 of devices running in parallel, all on a silicon-and-glass chip.

Outside Academic Research Use: Electrode Coatings for Neurostimulation The exchange of charge (and information) between biological systems (ion-containing solutions) and implantable electrodes (conduction electrons) can be facilitated using large surface area or reactive coatings. Iridium oxide (IrO2) coatings have been investigated for this purpose. These have been synthesized using reactive sputter deposition and characterized at the Singh Center. Under some deposition conditions, including increased deposition pressure, oxygen partial pressure, or temperature, a striking microstructure, as shown in Figure 2, is observed. The microstructure can be adjusted by changing the deposition parameters. Images of example microstructures are shown, all at the same magnification, in Figure 1.

A Single Mask Process for the Realization of Fully-isolated, Dual-height MEMS Metallic Structures Separated by Narrow Gaps Multi-height metallic structures are of importance for various MEMS applications, including master molds for creating 3D structures by nanoimprint lithography, or realizing vertically displaced electrodes for outof-plane electrostatic actuators. Normally these types of multi-height structures require a multi-mask process with increased fabrication complexity. In this work, a fabrication technology is presented in which fully-isolated, dual-height MEMS metallic structures separated by narrow gaps can be realized using a selfaligned, single-mask process. The main scheme of this proposed process is throughmold electrodeposition, where two photoresist mold fabrication steps and two electrodeposition steps are sequentially implemented to define the thinner and

thicker structures in the dual-height configuration. The process relies on two selfaligned steps enabled by the electrodeposited thinner structures: a wet-etching of the seed layer utilizing the thinner structure as an etch-mask to electrically isolate the thinner and the thicker structures, and a backside UV lithography utilizing the thinner structure as a lithographic mask to create a high-aspect-ratio mold for the thicker structure through-mold electrodeposition. The latter step requires the metallic structures to be fabricated on a transparent substrate. Test structures with differences in aspect ratio are demonstrated to showcase the capability of the process. This work has been recently published in the Journal of Micromechanics and Microengineering, 2018, 28 (2) 027001, “A single mask process for the realization of fullyisolated, dual-height MEMS metallic structures separated by narrow gaps,” Yuan Li, Min Soo Kim, and Mark G. Allen.

Devices for Smart Soil Moisture Monitoring Plasmonic nanostructures provide excellent platforms for colorimetric sensors in chemical, biological, and environmental applications. In contrast to the existing library of plasmonic sensors, an angle-independent optical sensor that is designed for monitoring soil moisture and operating on rough surfaces. The optical moisture sensor is constructed by coating hydrogel on top of an ultrathin, plasmonic Au nanorod lattice array, built at the Quattrone Nanofabrication Facility. The refractive index changes of the hydrogel upon exposure to moisture are transduced into spectral shifts of the resonances of the array. Robust, eco-friendly optical moisture sensors with angle-independent resonances provide a promising sensing platform for smart soil moisture monitoring important to tackle the challenge of water scarcity in agriculture.

2-D Materials Characterization and Device Fabrication Monolayer materials are sensitive to their environment because all of the atoms are on their surface. A group at Penn is investigating how exposure to the environment affects the electrical properties of CVDgrown monolayers of MoS2 by monitoring electrical parameters of MoS2 transistors as their environment is changed from atmosphere to high vacuum. The mobility increases, and contact resistance decreases simultaneously as either the pressure is reduced, or the sample is annealed in vacuum. A previously unobserved, non-monotonic change in threshold voltage with decreasing pressure was discovered. This result could be explained by charge transfer on the MoS2 channel and Schottky contact formation due to adsorbates at the interface between the gold contacts and MoS2. This project was done through a collaboration of the Marija Drndic and A.T. Charlie Johnson groups at the Department of Physics at Penn.

Penn Engineering Research Gives Optical Switches the ‘Contrast’ of Electronic Transistors Current computer systems represent bits of information — the 1’s and 0’s of binary code — with electricity. Circuit elements, such as transistors, operate on these electric signals, producing outputs that are dependent on their inputs. As fast and powerful as computers have become, Ritesh Agarwal, professor in the Department of Materials Science and Engineering, knows they could be more powerful. The field of photonic computing aims to achieve that goal by using light as the medium. In a paper published in Nature Communications, he and his colleagues have taken an important step: precisely controlling the mixing of optical signals via tailored electric fields, and obtaining outputs with a near perfect contrast and extremely large on/off ratios. Those properties are key to the creation of a working optical transistor.

Agarwal Lab members Ming-Liang Ren, Jacob S. Berger, Wenjing Liu and Gerui Liu all contributed to the research. This research was supported by the US Army Research Office through grants W911NF-11- 1–0024 and W911NF-12-R-0012–03, and the National Science Foundation through a Materials Research Science and Engineering Center seed grant, award number DMR11– 20901. Nanofabrication and electron microscopy characterization was carried out at Penn’s Singh Center for Nanotechnology.

To address this issue, Agarwal’s research group started by finding a system which has no background signal to start: a nanoscale “belt” made out of cadmium sulfide. Then, by applying an electrical field across the nanobelt, Agarwal and his colleagues were able to introduce optical nonlinearities to the system that enable a signal mixing output that was otherwise zero. “Our system turns on from zero to extremely large values, and hence has perfect contrast, as well as large modulation and on/off ratios,” Agarwal said. “Therefore, for the first time, we have an optical device with output that truly resembles an electronic transistor.”

Figure A shows a diagram of the the Agarwal research group’s “nanobelt.”

Wednesday Open Process Sessions

Cleanroom Summer School

Each Wednesday, staff members hold an open forum for users in the Mid-Atlantic community. The primary purpose of the event is assembling Singh Center staff with researchers to offer solutions to their fabrication problems â&#x20AC;&#x201C; ranging from simple devices to complex multi-level process integration issues. It also allows researchers with limited backgrounds in fabrication to learn how staff and their community peers design devices and work through the challenges of device fabrication.

The Quattrone staff have continued to develop and implement its Cleanroom Summer School, open to all. The course consists of a series of lectures, device design sessions, advanced processing applications and some hands-on fabrication techniques. Topics include lithography (optical, imprint, direct write), reactive ion etching, thin film deposition (thermal, electron beam, sputtering), process metrology, and Design of Experiments. These lectures and demos were held throughout the summer. Over 100 attendees participated in at least one of the sessions of the Cleanroom Summer School last year; approximately 20% of the participants were from other universities or industry.

2017-2018 Annual Report Singh Center for Nanotechnology

Cleanroom Boot Camp In addition to the Cleanroom Summer School, the Singh Center staff developed a more intensive “boot camp”. This two-day program teaching basic nanofabrication techniques consisted of both lectures and an in-fab workshop. The lectures consisted of the following fundamental processes for nanofabrication: • Plasma Enhanced Chemical Vapor Deposition) • Resist application and contact lithography • Reactive Ion Etching • Key metrology techniques for monitoring the thin film deposition, lithography, and etch processes The workshop portion included gowning up for the cleanroom and applying the lecture principles on the actual tools over two days. Twelve participants were able to gain hands-on experience with photolithography, plasma etching, deposition, and characterizations. The participants took home a processed 100mm silicon wafer that they used throughout the boot camp program.

The Seed Grant program was developed to encourage the use of the facilityâ&#x20AC;&#x2122;s resources by providing grants for equipment use, ranging in size from a few hundred to a few thousand dollars, to start-up and small companies. The program is launched in the spring of each year. Applicants submit proposals describing their projects and goals and Singh staff evaluate them over several meetings. Final applicants review the scope of work with the staff in-person or remotely in the form of a presentation and Q&A before funding decisions are made.

2018 Seed Grant Winners The 2018 Singh Center for Nanotechnology recently announced the recipients of the 2018 Seed Grant Competition awards. The grants are providing $17,500 in laboratory and equipment time funding for nine startup and entry-level businesses. In addition, the program has been expanded to allow up to two successive years of funding if judged appropriate by the staff.

Microfluidics Workshops Staff members, led by our Soft Lithography Lab manager Eric Johnston, continue to host monthly Microfluidic Workshops as a form of outreach to local university medical schools (Penn, Drexel, Temple, Jefferson and Cooper) as well as to other researchers in the region. We continue to target MD/PhD (research driven) programs and have now added several more industrial researchers. The workshop format of the core course remains the same as that described in previous reports: Researchers enroll in a six-hour session that consists of lectures and hands-on device fabrication. Each researcher provides a design of interest for the workshop that will be built into a functioning device by the end of the day.

We continue to find that researchers make use of our library of device designs for particle sorting, gradient generation, and fluid mixing. Over 120 people have participated in this program from May 2017 to April 2018. In the past year, two advanced workshops, (Solving Problems in Microfluidics, and Two-Level Microfluidic Fabrication) were added to complement the core program.

Annual NNCI Meeting Over 80 participants from the 16 member sites, the NSF, and the NNCI Advisory Committee attended the NNCI conference, hosted by the Singh Center for Nanotechnology. The first day included site overviews from their directors, and this year the overviews were presented in the form of short presentations followed by panel discussions. The four topics of these panel discussions: Redefining Traditional Roles; Resource Allocation and New Equipment; Future Research Directions; and New Education and Outreach, were chosen to help the sites understand how to best serve our users. The panels invoked lively questions, answers, and comments from the participants. On the second day of the conference, breakout sessions looked into Facility Management, Diversity, New Business Development Concepts, and Training Programs and Workshops. These sessions were followed by a review of the discussions before all of the attendees. The meeting concluded with an Advisory Board Report. Parallel meetings were held to discuss nanotechnology education and nanotechnology societal and ethical implications. Two technical talks were presented at the conference: Professor Mehdi Javanmard from Rutgers University described research his group is conducting at the Singh Center on electro-fluidic nanotechnology, which provided an outside academic user perspective; and Professor Eric Stach from the University of Pennsylvania, who described the new research avenues he expects to pursue with the electron microscope suite the center is currently installing.

NNCI Commercialization Committee

NNCI Equipment, Maintenance and Training Working Group

The NNCI Commercialization Committee, consisting of W. Wilson, D. Dickensheets, K. Walsh, T. Thornton, Y. Lo, D. Herr, M. Allen (chair); and G. ’Pat’ Watson (staff), met in April 2018. The Committee is charged with understanding, promoting, assessing, and reporting on the commercial and translational impact of the NNCI Sites and the NNCI Network.

Meredith Metzler, a Singh Center senior manager and an expert in thin film processing, is currently the chair of the Equipment, Maintenance and Training Working group (EMT). The working group is tasked with identifying and addressing issues that affect member sites in the areas equipment, maintenance, and training. Early conversations have focused on cost saving measures related to equipment operations and upkeep. As an example, each facility faces financial constraints that require aging equipment to be kept operational rather than being replaced. Many facilities in the network have aging fleets of tools and systems that are becoming more resource intensive to maintain. By leveraging our experience and relationships, both within the network and with equipment vendors, we feel there is an opportunity to collectively address these challenges.

To this end, the Committee discussed a number of tasks to impact translation of NNCI-enabled technology, including: assessment of NNCI site and network economic impact; collection of commercialization best practices and ‘success stories’; understanding what programs can be recommended to the nodes to foster commercialization;understanding how university nodes can connect existing or newly developed educational programs (e.g., in entrepreneurship) to further commercial impact of the NNCI; and to identify ways that the network can be more than the sum of its parts when it comes to commercialization and translation of nanotechnology.

The working group now consists of members representing University of Pennsylvania, Stanford University, University of Texas - Austin, Cornell University, University of North Carolina Chapel Hill, and University of Washington is planning to meet in September at Stanford University during the NNCI Etch workshop.

2017-2018 Initiatives Network Activities

NNCI Photolithography Working Group Pat Watson, Director of User Programs, along with staff engineers David Jones and Gyuseok Kim, are leading this new working group. Photolithography is an essential component of micro- and nanofabrication technology and is available in some form in all cleanroom facilities. However, there are restrictions on the substrate size, the topography of the substrate surface, the chemistry of the substrate surface, resist type and thickness, and especially feature size, that limit the type of devices some researchers can construct at some facilities. This working group intends to construct a database of the expertise and special equipment available across the network so that when researchers have unique requirements, site staff can search to see if a process is available to help create in-house capability, or which network lab can run the process for that user. A database would also allow the working group to identify where gaps in capabilities are, and what new equipment or process development may be required in the future. The database would make use of the new capabilities that are planned for the NNCI website; a password-protected part of the site may be used to store, grow, and share this information across the network. A public access version of this information will also be made available. The database can be expanded in the future to keep track of other capabilities, such as lithography simulation software. Members of cleanroom staff from 9 NNCI sites are participating in the Photolithography Working Group. They are: • • • • • • • • • • •

Node-To-Node Research Collaboration

Singh Center for Nanotechology Leadership on NNCI Cost Savings

The Singh Center for Nanotechnology has made use of equipment andcollaborated with the following NNCI partner sites:

At the Singh Center, as with other NNCI sites, we rely deeply on excellent relationships with our suppliers and competitively bid all purchases to achieve best pricing, particularly in the area of consumables. This activity is spearheaded by Charles Veith, a staff member from our Center. Last year, the Singh Center for Nanotechnology was able to secure materials such as high purity gold and electron beam resist at much lower costs and pass those savings onto other NNCI sites. Recent purchasing highlights from the Singh Center consist of:

• The Singh Center provided LPCVD SiNx deposition and annealing services to the NNCI partner the University of Washington. • Cornell CNF and the Singh Center continue to assist each other on several fronts. The CNF has provided anti-stiction coatings to Singh users for nano-imprinting. The CNF has also provided BPSG deposition services and SiNx ALD coatings to Singh researchers. • We have assisted the Cornell CNF with ellipsometry measurements, and with supplying XeF2 for Si etching. We also helped them restore equipment capability by assisting with a turbomolecular pump swap. • We have helped node member the University of Minnesota with supplies of the e-beam lithography resist ZEP 520A.

•

Providing an alternative source for PDMS curing agent. Dow Chemical has had difficulties providing this vital component for microfluidic device fabrication. The Singh Center identified Gelest as another source and shared this information with other network nodes.

•

Bulk purchase of XeF2. The Singh Center for Nanotechnology has purchased a relatively large quantity of this important gas-phase Si etchant at a substantially lower cost and is providing it to Network labs (and other government and academic labs) including Cornell.

•

Alternative for O-rings for vacuum systems. The Singh Center for Nanotechnology has had identified a new domestic supplier of these vital parts of vacuum equipment. The new supplier is giving a 30 to 60% reduction in cost and substantial reduction in lead-time.

• Expendables discount information has been shared with other NNCI sites and will lead to a 40% reduction in costs of these materials. We intend to fold this activity into the NNCI vendor relations working group, currently chaired by Michael Khbeis from the University of Washington’s NNCI nanofab facility.

Local College Educational Outreach: Swarthmore College Seven students from Prof. Kyle Wagnerâ&#x20AC;&#x2122;s Swarthmore College course â&#x20AC;&#x2DC;Topics in Surface Chemistry and Surface Analysisâ&#x20AC;&#x2122; visited The Singh Center for Nanotechnology in April 2018 for a presentation and in-cleanroom demonstration of fabrication technology. The course is seminar style and intended for junior and senior chemistry majors and minors. A theme of the course is based on the ability to design and specifically modify surfaces at the molecular level and how this enables miniaturization of many technologies. Topics include methods to fabricate micropatterned surfaces, and techniques used to characterize surfaces chemically and spatially using microscopy and surface spectroscopies. The students were introduced to fundamental components of micro and nano fabrication technology in the cleanroom. They were given hands-on experience with photolithography, plasma etch, and deposition tools and processes. In total, seven students visited the Singh Center, and all are graduating this Spring. Of the students who visited, one student is an engineering major, while the other six were chemistry or biochemistry majors (one dual major with math). Three of the students are attending graduate school this Fall and will study chemistry or chemical engineering. Three other students plan to attend graduate school or medical school after a gap-year. The success of this program has encouraged the Singh Center to reach out to other local colleges.

K-12 Outreach Collaboration During the 2017-2018 academic year, the Singh Center, and the Laboratory for Research on the Structure of Matter (LRSM) hosted monthly field trips for Philadelphia middle and high school students. During these visits, students had introductory lessons on Nanotechnology and Materials Science, had lunch, and went on campus tours. Some students also suited up for the clean room at the Quattrone Nanofabrication facility, where they observed and, when possible, assisted with lithography, etching, and soft-lithography. Over the course of the year, 124 students from four schools participated in the field trip program, of which 81% were under-represented minorities and 96% were low-income. All expenses (including transportation, lunch, and supplies) were covered for participating schools. One example of this activity is our centerâ&#x20AC;&#x2122;s hosting a visit for students attending the Boyâ&#x20AC;&#x2122;s Latin of Philadelphia Charter School last year. Twenty-five students from this school gowned up and toured the cleanroom, and participated in lithography, etch, and microfluidics processing activities. Singh Staff also participated in career day events at the near-by Alexander Adaire Elementary school in May 2018. Staff explained the principles of nanofabrication through presentations with handouts and cleanroom gowning demonstrations throughout the day for kindergarten to 8th grade students.

Site Curricular Education

ESE 536 – Nanofabrication and Nanocharacterization

MSE 610 –Transmission Electron Microscopy And Crystalline Imperfections

This course was developed and offered for the first time in the Center for Nanotechnology facilities in Spring 2017; it ran again in Spring 2018 and is intended for first year graduate students interested in the experimental practice of nanotechnology. There continues to be a heavy demand from students based on registration and 19 students took part this year.

This course describes the theory and application of transmission electron microscopy methods to problems in materials science and engineering, condensed matter physics, soft matter, polymeric materials, inorganic chemistry and chemical engineering. The principles of microscope operation, electron scattering, image formation and spectroscopy will be described, with an emphasis on both theory and experiment. This year, hands-on laboratory work using the Nanoscale Characterization microscope facility was emphasized.

Students gain familiarity with both top-down and bottom-up fabrication and characterization technologies with hands-on device fabrication. This is achieved through the realization of a variety of microand nanoscale structures and devices that can exhibit either classical or quantum effects at the small scale. Although concepts relevant to the laboratories are emphasized in lecture, it is expected that students will already have been exposed to many of the underlying theoretical concepts of nanotechnology in previous courses. Last year’s teaching assistants went on to a career at Global Foundries and to graduate schools at the Universities of Connecticut and Pennsylvania. Students from that first class went on to intern at NASA and the Jet Propulsion Laboratory. Students from this year’s class are using the skills they they learned in the course by interning at Micron Semiconductor, Trumpf Photonics, and Boeing this summer.

2017-2018 Annual Report Singh Center for Nanotechnology

MEAM 537 Nanomechanics and Nanotribology Engineering is progressing to ever-smaller scales, enabling new technologies, materials, devices, and applications. This course provides an introduction to nano-scale tribology and the critical role it plays in the developing areas of nanoscience and nanotechnology. We discuss how contact, adhesion, friction, lubrication, and wear at interfaces originate, using an integrated approach that combines concepts of mechanics, materials science, chemistry, and physics. We cover a range of concepts and applications, drawing connections to both established and new approaches. We discuss the limits of continuum mechanics and present newly developed theories and experiments tailored to describe micro- and nano-scale phenomena. We emphasize specific applications throughout the course. Reading of scientific literature, critical peer discussion, individual and team problem assignments, and a peer-reviewed literature research project is assigned as part of the course.

MSE 250 Nanoscale Materials Laboratory The course provides an in-depth experimental introduction to key concepts in materials and the relationships between nanoscale structure, their properties and performance. The use of laboratory methods to examine the structure of materials, to measure the important properties, and to investigate the relationship between structure and properties is covered. Emphasis is placed on a complete exposure of Nano- and Materials science as a field. Most experiments require multiple laboratory sessions, with priority given to experiments in which students explore the entire range of materials science, from the synthesis of materials and the characterization of structure, thermodynamics and composition, to the measurement of properties and discussion of applications. Students are able to realize working devices as an end product of the key laboratories in this course. Practice in oral and written communication is realized through course assignments.

Graduate Student Fellows Program Understanding the gap that exists from academic learning to practical experience for young professionals is an issue the Singh Center for Nanotechnology has chosen to address. Under the direction of Noah Clay, and Guyseok Kim, the Quattrone Nanofabrication Facility has instituted the Graduate Student Fellows (GSF) program to provide Master's students with hand's on instruction in cleanroom device fabrication to complement their academic education. A total of ten master students at Penn engineering were chosen as Graduate Student Fellows (GSF). Conceived in 2015 by Noah Clay, Staff Director of the Quattrone Nanofabrication Facility (QNF), the GSF program is a highly regarded and competitive program that provides Penn masters students with nanofabrication experience in a world class cleanroom. The GSFs will develop hands-on skills in fabricating devices, establishing fundamental and advanced level processes, and developing and participating in educational components for lab courses and workshops. “We want the GSFs to have hands-on nanofabrication experiences which cannot be obtained by textbook”, Gyuseok Kim, GSF program coordinator, mentioned. For a year, each student makes their own device, such as multichannel biosensors, transducers for cochlear implants, nanopore membranes, MEMS devices, 2-D graphene sensors, and quantum dot devices. Projects are collaborations with Penn faculty as well as faculty from other institutions, such as Children’s Hospital of Philadelphia and UFPR in Brazil. While GSFs develop their device, they will also learn how materials and tools are used in the processes, and how to troubleshoot. “Another purpose of this program is to share our knowledge to the world”, Gyuseok added. As a member of National Nanotechnology Coordinated Infrastructure (NNCI), QNF has shared the protocol and tool data since 2015 through Scholarly Commons. As a team, GSFs are building a community to share the nanofabrication experience through weekly meetings to discuss and share progress on their devices and processes. Each GSF presents to the team every third week, giving them the opportunity to practice public speaking and professional development. Since 2015, the GSF program at QNF has become an integral and vital element of the continuing goal of service to the University of Pennsylvania as well as to the wider academic and business communities.

Marketing and Communications Website

Newsletter and Other Documents

We have made a substantial effort in social media engagement this year, beginning with the relaunch of the Singh Center website. The objective of the site development re-design was to increase the visibility of the centerâ&#x20AC;&#x2122;s programs and initiatives. Elements of the new design allow for a direct search of our inventory of equipment and tools. News and events are now prominently displayed on the top third of the home page to share upcoming information and events. The number of our menu categories on the homepage navigation bar has been increased from 4 to 7 (now including Education, Initiatives, and Facilities) that chronicle additional engagements of the Singh Center for Nanotechnology.

John Russell, Program Coordinator, has created a digital newsletter in the past year, intended to provide our mid-Atlantic community with current information about our center-related activities. Each issue includes sections on recent activities of faculty, research, and information about upcoming programs and events. In addition to the newsletter, Russell has digitized our annual reports and facility brochures to provide downloadable versions of these informational resources to our network. Social Media Presence John Russellâ&#x20AC;&#x2122;s social media efforts in Twitter and Facebook have produced sizeable increases of audience engagement. The production of posts on these platforms have been comparable from the previous year, with an audience reach of 19,970 in 2017 to 40,074 in 2018 (a 101% increase). Twitter impressions for the Singh Center for Nanotechnology have also shown a substantial rise in viewer connections, with 23,230 impressions in 2017 to 37,114 in 2018 (a 60% increase).

2017-2018 Initiatives Community Outreach

Nanotechnology Technicians Training Program The Community College of Philadelphia (CCP) and the Singh Center organized two meetings for industry representatives to provide their thoughts about the need for and structure of a nanotechnology technicians training program. The first meeting was on August 31, 2017 at the Singh Center and the second was held at CCP on December 12, 2017. The meetings were attended by 12 and 6 external participants, respectively. Participants were selected as representatives of industry that would be potential future employers of nanotechnology technicians. Discussion centered around the skills and training the participants felt would be necessary for success of newly hired technicians in their companies, labs or industries more generally. Despite most participants stating that their companies were currently or would in the future be interested in hiring technicians with the type of nano- and/or micro-scale training discussed in the meetings, the evidence that the opportunities would be hyperlocal was less strong. Most CCP students would be seeking work that is within commuting distance from Philadelphia. Thus, CCP decided to begin its training program by adding a single nanotechnology course to its curriculum, rather than a full program, and observe how the uptake and interest progressed from that course.

The industry meetings also revealed that training in additive manufacturing could provide skills that make students competitive for local jobs. Based on this information, CCP plans to start a course focused on additive manufacturing, in addition to the new course in nanotechnology. The Singh Center for Nanotechnology is also in a position to inform this course due to its partnership with and co-investment in equipment in Penn’s Additive Manufacturing Laboratory. Towards these aims, CCP has outlined the nanotechnology course content with feedback from the Singh Center, and over the summer, will flesh out the laboratory activities for the course. The expected timeline is that the course development and CCP administrative approval process will be completed during Fall 2018 and that the course will be offered in Spring 2019. Course and lab content are also being informed by materials used by the NACK Network, nanoHUB, Nano-Link and peer NNCI sites involved with curriculum-design at community colleges to leverage existing resources and expertise. The new Nano course would follow CCP’s standard of designing courses that allows for smooth transfer of credit for students who pursue bachelor’s degrees in four-year institutions. CCP courses typically enroll 12-24 students per semester. The impact of the Nano course on students’ future job and academic interests would help CCP further evaluate whether building a larger nanotechnology program would serve both students and local employers. For the additive manufacturing course, CCP has started to collect initial information about the appropriate content by meeting with the Penn Engineering AddLab staff, a partner of the Singh Center, which supports multiple courses in Penn’s Department of Mechanical Engineering and Applied Mechanics. wCCP plans to further discuss with members of the local advanced manufacturing industry about strategic training in this area.

2017 Annual User Meeting The annual User Meeting was held on October 17-18th at the Singh Center for Nanotechnology. This event was designed to showcase the research being done by the Singh Center’s User Community, along with that of the greater Mid-Atlantic Research Community. It also provided a platform to increase nanotechnology awareness and demonstrate specific applications of the technology. As in the past, the conference was broken into specific segments designed to appeal to broad range of interests and backgrounds. This year we featured nanotech in medicine, energy and the environment, and entrepreneurship, in addition to a segment featuring research being done solely by the Singh user community. On the first day of the event, a cross-section of the Singh Center’s User Community presented work on topics ranging from the creation of new coating for biomedical electrodes to learning about how companies like ExPonent regularly use the Singh Center’s facilities to conduct failure analysis. The next day’s activities were directly focused on the advances from the Singh Center’s user community. Highlights included presentations by Dr. Brian DiPaolo from Halo Lab, Dr. Steven Baxter from Arkema, Dr. Matthew Sfeir from Brookhaven National Labs and Dr. John Lettow from Vorbeck Materials.

Mid-Atlantic Electron Beam Lithography Workshop The 2nd annual Meeting for Advanced Electron Beam Lithography workshop was held at the University of Pennsylvania Singh Center for Nanotechnology in April 2018. The meeting provided an intimate space to bring together the community to openly discuss topics devoid of conference formality and hardware vendors. The purpose of the meeting was to connect active novice to experienced tool owners and users to exchange practical and directly applicable knowledge. Structured talks, lectures and planned discussions in additional to over three hours of networking is built into the one-day program.Topics included novel processing with HSQ and epitaxial growth; demystifying proximity effect correction; leveraging scripting to automate data creation, preparation and exposure; discussing common issues in EBL; optimizing shape fidelity through proper shot placement; and fabricating superconducting quantum bits (qubits).
