Abstract
ABSTRACTGaN was grown by supersonic jet epitaxy(SSJE), seeding triethylgallium in helium carrier gas. Activated nitrogen was supplied by a microwave plasma source. Single crystalline GaN films were deposited on the Si-face 6H-SiC and the c-plane sapphire substrates at 600–670°C. A cubic SiC buffer layer was grown onSi(111) at 800°C by SSJE using dichlorosilane, acetylene, and a high quality GaN crystal was grown on this template at 630°C. The materials high quality was proved by hard rectifying characteristics of a diode with an N-GaN/β-SiC/P-Si(111) structure.
