摘要
A high-quality thin (11 (2) over bar0) GaN layer with an atomically flat surface has been successfully grown on a. precisely offset-angle-controlled (1 (1) over bar 02) sapphire substrate by metal-organic vapor phase epitaxy. The insertion of an AlGaN layer between the underlying AlN layer and the GaN layer was found to improve the crystalline quality of the upper GaN layer.
