Herbert Kroemer , a professor of electrical and computer engineering at the University of California, Santa Barbara, with a dissertation on hot electron effects in the then-new transistor, setting the stage for a career in research on the physics of semiconductor devices. In 2000, Kroemer, along with Zhores I. Alferov, was awarded the Nobel Prize in Physics "for developing semiconductor heterostructures used in high-speedand opto-electronics" . The other co-recipient of the Nobel Prize was Jack Kilby for his invention and development of integrated circuits and micro-chips.
