Flexible Electronics for Space Applications: Development of New Materials and Device Processing Technologies South Dakota School of Mines and Technology/NASA Glenn Research Center, Jet Propulsion Laboratory, Langley Research Center, Space Technology Mission Directorate

Laser Interference Patterning of III-V Semiconductor. Atomic force microscope (AFM) images of two different patterns of nanowires produced by a single application of Interferential Irradiation of Laser Pulses (IILP). (a and b) Nano strips ~30 nm wide with trenches 5 nm deep. (d) Wider nanowires (100 nm with trenches 5 nm deep). (c and e) Line profiles for (a) and (c), respectively.

We continue working toward the goal of the project, which is to develop new materials and technologies that enable light-weight, conformable, flexible, and stretchable electronic devices and sensors for space applications. We have made solid progress in research, education, and economic development in this year. Improvements in jurisdiction research and development infrastructure: Co-I Zhu received an infrastructure improvement grant from South Dakota Board of Regents to acquire an electrochemical system. Co-I Smith received NSF MRI award to acquire an advanced AFM system, and Co-I Qiao received NSF MRI award to develop novel instrumentation to probe nanoscale charge carrier dynamics. Co-I Qiao also purchased an electrochemical testing station with this NASA grant. These awards substantially enhance our research infrastructure. Increased financial commitment from the jurisdiction, industry, and participating institutions: Co-I’s Zhu, Qiao, Zhang, Ahrenkiel and Smith have received Grants from South Dakota Board of Regents, NSF, and industries in 2014. Response of activities to NASA and jurisdiction

priorities: The State Research priorities, as outlined in “2020 Vision: The South Dakota Science and Innovation Strategy” (2013), include Information Technology, Value-Added Agriculture and Agribusiness, Energy and Environment, Human Health and Nutrition, and Materials and Advanced Manufacturing. Co-Is have actively worked on research in advanced materials and energy technologies and submitted proposals to secure funding for their research. Co-PIs are also actively working on the energy-related technologies that have been identified as priorities by NASA, such as advanced battery and photovoltaic technologies. Reordered jurisdiction and/or institutional priorities: Co-I Ahrenkiel submitted a seed proposal in collaboration with Dr. Jeremiah McNatt from the Photovoltaic & Electrochemical Systems Branch at NASA Glenn Research Center. Co-I’s Zhu and Qiao have worked on preliminary research on battery technologies that responds to NASA technology priorities. Co-I’s Zhu, Qiao, Smith have successfully received grants from the State of South Dakota, NSF, and private companies to improve their research capabilities in these areas.
