摘要
High quality AlGaN/GaN heterostructures have been grown by metalorganic vapor phase epitaxy (MOVPE). The crystal quality was investigated by X-ray diffraction and Rutherford Backscattering (RBS). Cracking was observed near the interface of the AlGaN and GaN epilayer when the thickness of AlGaN layer exceeds a critical value. Following Matthews' model, a calculation of the critical thickness was performed which agrees with the experiment. (C) 1998 Elsevier Science Ltd. All rights reserved.
