摘要
We have found that MgO deposited on c-Al2O3 substrates at high temperatures formed MgAl2O4 by interdiffusion during MgO layer growth, The formation of spinel MgAl2O4 has been confirmed by in-situ reflection high energy electron diffraction (RHEED) and grazing incident X-ray diffracition (GIXD). The critical temperature (T-C) for the formation of MgAl2O4 was found to be around 700 degrees C above which MgAl2O4 is formed at the MgO/c-Al2O3 interface. (c) 2007 WILEY-VCH Verlag GmbH &,Co.
