0.013 at.%的H_2O的相互作用采用亚稳态诱导电子能谱(MIES)、紫外光电子能谱(UPS)和X射线光电子能谱(XPS)对Fe掺杂的SrTiO 3(100)进行了研究。应用低能电子衍射(LEED)来收集有关表面终止的信息。为了消除表面缺陷的影响,未处理和弱溅射SrTiO 3表面进行了研究。溅射导致在表面层中形成与氧相关的缺陷。未经处理的SrTiO 3表面与H2O的相互作用很弱。由于其极端的表面灵敏度,只有MIES才能识别少量的OH基团。溅射表面显示出更大的OH形成。未观察到非解离H2O吸附。因此,我们得出结论,暴露于SrTiO 3(100)的H2O的结果在附近的表面缺陷的解离,导致在表面羟基的形成。版权所有© 2010约翰威利父子有限公司.
The interaction of H2O with 0.013 at.% Fe‐doped SrTiO3(100) was investigatedin situwith Metastable Induced Electron Spectroscopy (MIES), Ultraviolet Photoelectron Spectroscopy (UPS) and XPS at room temperature. Low Energy Electron Diffraction (LEED) was applied to gather information about the surface termination. To clear up the influence of surface defects, untreated and weakly sputtered SrTiO3surfaces were investigated. The sputtering results in the formation of oxygen‐related defects in the top surface layer.The interaction of untreated SrTiO3surfaces with H2O is only weak. Small amounts of OH groups can be identified only with MIES due to its extreme surface sensitivity. Sputtered surfaces show a larger OH formation. Nondissociative H2O adsorption is not observed. We therefore conclude that the exposure of H2O to SrTiO3(100) results in the dissociation near surface defects only, resulting in the formation of surface hydroxyl groups.
