Gelu (Jerry) Comanescu (Fed)

Dr. Jerry Comanescu received an undergraduate degree in Physics from the University of Bucharest, Romania and a Ph.D. degree in Physics from the State University of New York at Buffalo. He is presently a physicist in the Functional Nanostructured Materials Group of the Materials Science & Engineering Division. Dr. Comanescu’s current research efforts are focused on wide bandgap semiconductors materials and devices for power electronics and RF applications. One of his current research focus areas is TCAD modeling of GaN/AlGaN semiconductor devices such as GaN-HEMTs, GaN-diodes, and Vertical GaN FET power devices. Another research focus area is electrical and optical characterization of semiconductor devices, nanostructured materials, and low-dimensional electron systems. Jerry’s technical expertise and interests span several technical areas, such as optics, photonics, spectroscopy, lasers, sensors, nanotechnology, semiconductor materials & devices, and others.
