  • Abstract
    GaN/SiC p-n junctions for heterojunction bipolar transistors have been fabricated using photoelectrochemical etching. The process was shown to have excellent selectivity between n- and p-type semiconductors, self-terminating at the p-type SiC layer. Smooth p-SiC surfaces were observed, and contact resistance on the etched surface of 3×10-3Ω·cm2 was achieved. This process has been used in the fabrication of HBTs
