摘要
A microstructural analysis of m-plane GaN and AlGaN layers grown by metal-organic vapor phase epitaxy using the epitaxial lateral overgrowth method was carried out. It was difficult to reduce stacking fault density when stripes were formed along the < 0 0 0 1 > direction, which implies that stacking faults originate from c-plane slip. In the case of stripes along the, < 11 (2) over bar0 > directions, both stacking fault and threading dislocation densities can be reduced. (c) 2006 Elsevier B.V. All rights reserved.
