摘要
The GaN/(0001) Al2O3 interface was investigated by HREM. Steps of height c(substrate)/3 = 0.433 nm were found to give rise to extended defects in the epitaxial layer. These defects are inversion domains whose boundary atomic structure was found to be described by the Holt model. A geometrical analysis shows that such inversion domains call form on steps in order to minimize the misfit along the c-axis. (C) 1999 Elsevier Science S.A. All rights reserved.
