Valence band behaviour of zirconium oxide, Photoelectron and Auger spectroscopy study

Abstract In this study X-ray Photoelectron Spectroscopy and Ultraviolet Photoelectron Spectroscopy were combined to investigate the effect of oxygen incorporation on the valence band behaviour of ZrO x . The Auger transitions involving valence bands are found to mimic the self-folded density of stat...
