中文摘要	The morphology of AlN crystal grown under the same growth conditions by the PVT method on four kinds of 4H-SiC substrates (SiC (0001), SiC (000 - 1), 8 degrees off-axis SiC (0001), and 8 degrees off-axis SiC (000 - 1), off-oriented from the basal plane toward the < 11-20 > direction) was investigated. It is found that the nucleation more easily occurs on the Si face substrate than on the C face substrate at 1800-1900 degrees C. Hexagonal flakes nucleated on the SiC (0001) substrate, while tetrahedral grains nucleated on the 8 degrees off-axis SiC (0001) substrate. AlN grown on the 8 degrees off-axis SiC (000 - 1) substrate was strikingly different, and flower pattern structure AlN deposited on the substrate. A stepped structure with smooth terraces was obtained on the 8 degrees off-axis SiC (0001) substrate at 1900 degrees C for 4 h. We conclude that the AIM grown on the 8 degrees off-axis SiC (0001) substrate was first by island nucleation then by the step-flow growth mode. (C) 2012 Elsevier Ltd. All rights reserved.
