Abstract
An anomalous behavior was observed in X-ray photoelectron Spectroscopy (XPS) depth profile measurements conducted on CeO2/Si epilayers grown by ion beam epitaxy (IBE): the signals of Ce3+ and Ce4+ co-exist, and the ratio between them increases during the etching time and then ten ds to maintain a constant level before increasing again. The results o f X-ray Diffraction (XRD), Auger Electron Spectroscopy (AES), and Ruth erford Back-Scattering (RES) measurements proved that the reduction ch emical reaction of CeO2 is induced by ion-etching.
