A detailed study of resonant photoemission at Ti L(2,3) edges of insulating rutile TiO(2-x) thin film is presented. Pure TiO(2) resonating structures, defect-related resonances, resonant Raman-Auger and normal LVV Auger emissions are tracked, including an unpredicted two-hole correlated satellite below the non-bonding part of the valence band. The analysis of excitation dynamics unambiguously addresses the origin of these features and, in particular, the extent of charge transfer effects on the Ti-O bonding in the valence band of rutile, disclosing further applications to the more general case of, formally, d(0) oxides.
本文详细研究了绝缘金红石 TiO(2-x) 薄膜钛 L(2,3) 边的共振光发射。跟踪了纯 TiO(2)共振结构、与缺陷相关的共振、共振 Raman-Auger 和正常 LVV Auger 发射，包括在价带非键部分下方未预测的两个空穴相关卫星。激发动力学的分析明确了这些特征的起源，特别是对金红石价带中 Ti-O 键合的电荷转移效应的程度，进一步揭示了在更一般的形式上，d(0)氧化物的情况下的应用。
