Defects and Related Carrier Traps in GaN AlGaN and Implanted SiC
In this project, work has been performed on nine different topics: (1) Ultra-fast microwave annealing of ion-implanted 4H-SiC ; (2) Silicon carbide nanowires grown by a novel microwave heating-assisted physical vapor transport process; (3) Depth resolved X-ray determination of surface strain in free-standing films of HVPE-grown GaN and 71Ga NMR characterization (4) Effects of the surface and interface related defects in free-standing HVPE grown GaN films by high resolution X-ray diffraction measurements; (5) Bias stress induced instability in 4H-SiC DMOSFETs; (6) Stability and 2-D simulation studies of avalanche breakdown in 4H-SiC DMOSFETs with JTE; and (7) Power added efficiency and linearity tradeoffs in class AB biased GaN and GaAs microwave power HEMTs (8) High quality interlayer dielectric for 4H-SiC DMOSFETs; and (9)Thermally stable Ge/Cu/Ti ohmic contacts to n-type GaN. Important results on each topic are given in the attachment. We collaborated with Dr. Ken Jones of ARL on the......
