Transmission electron microscopy investigation of defects in B-implanted 6H-SiC

• Silicon carbide is due to its wide bandgap, high saturated electron drift velocity, high electric breakdown field and high thermal conductivity a suitable material for electron devices operating at high temperatures, high powers and high frequencies.[1,2] In order for SIC to reach its full potential in device technology, doping is essential. Usually ion implantation is used for doping since diffusion is difficult in SiC. Boron is a useful material for implantation because of its low atomic weight and greater penetration depth than other accepters, yet very few studies have been conducted on B-implanted 6H-SiC. [3,4] In this investigation we have used transmission electron microscopy (TEM) to study structural defects that are found in B-implanted 6H-SiC layers.
