摘要
The deposition of CeO2 on Si(111) has been studied by low energy electron diffraction (LEED), Auger electron spectroscopy (AES), x-ray photoelectron spectroscopy (XPS) and Rutherford backscattering spectroscopy (RBS). LEED shows the CeO2 layer to grow in the (111) orientation. The formation of a silicon oxide layer at the interface is observed. The thickness of this oxide layer is found to vary between about 1 and 8 nm, depending on the thickness of the CeO2 layer. A model for the growth of CeO2 and for the formation of the silicon oxide layer at the interface is proposed.
