XPS Research on SrTiO3-Based Voltage-Sensitive Material

摘要：

　　SrTiO3-based voltage-sensitive material was prepared successfully.The structure and properties were investigated using scanning electron microscopy,X-ray diffraction and X-ray photoelectron spectroscopy.It was observed that the average grain size was greater than 3μm and a cubic perovskite structure was obtained.XPS analysis of oxygen indicated that there existed multiform chemical state oxygen at the surface of the grain.Further researches shown that there were a few AO12 polyhedrons and many cation vacancies in the material discussed,which demonstrated that a lot of oxygen volatilized and a well-known semiconductivity level was achieved.
