Abstract

We have studied on the polarity selection procedure of ZnO grown on CrN buffer by using X-ray photoelectron spectroscopy (XPS). XPS studies have been performed on the O- and Zn-treated CrN/Al2O3surfaces and revealed that Cr2O3 and Zn-chromate-like structures are formed on O- and Zn-treated CrN surfaces, respectively. The polarity selection procedure is explained in terms of the variation of bonding coordination by the formation of ZnO on the topmost O- and Zn-atoms of each surface.
