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. The Auger transitions involving valence bands are found to mimic the self-folded density of state measured using Ultraviolet Photoelectron Spectroscopy. The valence band once constructed in a sub-oxide form, stays at a fixed energy position despite the change in the stoichiometry. This behaviour is found to be useful in setting a reference for X-ray Photoelectron Spectroscopy charge correction. The results of the charged corrected spectra were compared to other methods and found to be in great agreement. Finally, a correlation between the core-level binding energy and the structural property of ZrO is given.
在本研究中，结合X射线光电子能谱和紫外光电子能谱来研究氧掺入对ZrO价带行为的影响。发现涉及价带的俄歇跃迁类似于用紫外光电子能谱测量的自折叠态密度。一旦以亚氧化物形式构建价带，尽管化学计量发生变化，其仍保持在固定的能量位置。发现这种行为有助于为X射线光电子能谱电荷校正设定参考。将电荷校正光谱的结果与其他方法进行比较，发现结果非常吻合。最后，给出了芯能级结合能与ZrO结构性质之间的相关性。
