The rational growth and processing of nano-materials and structures including semiconductor heterostructures using CVD, MOCVD, solution growth, and by nanofabrication, have opened up interdisciplinary research in the areas of materials science, chemistry, solid state physics, and nanofabrication. With continuous reduction of device dimensions for faster operation, reduced power, and increased density and functionality, structure-property correlation at nano to atomic scales becomes vital to understand the influence of material design and their imperfections on their device performance.  This program will train student to explore the unprecedented opportunities in nano- and micro-scale engineered materials and devices, for a range of applications including a variety of semiconductor materials for microwave and mm-wave transistor operation, as well as for ultralow power; flexible electronics for human-computer interactions; determining limits of device scaling and performance; device modeling; developing advanced transistor circuits; and the integration of electronic and photonic devices.
