摘要：
The purpose of this study is to use high-angle annular-dark-field simulation to quantify aluminum fluctuation across the interface formed by a GaN-quantum dot and an AlGaN barrier layer. For this aim, a basic methodology with theoretical/numerical simulations has been carried out using nanometric, but not atomic, resolution range. A simple multislice method, based on simulations of the HAADF intensity scattered by a GaN/AlGaN interface was performed. Enrichment of aluminum near the GaN/AlGaN interface was confirmed by HAADF simulation. (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
