摘要

给出了SrTiO3(100)-(√13 ×√13)- r33.7°表面的扫描隧道显微镜成像。低能电子衍射图表明，在室温下沉积铁后，表面重构仍然存在。在SrTiO3(100)-(√13 ×√13)- r33.7°表面，Fe沉积产生了包括氧空位在内的缺陷。这些缺陷具有c(√13 ×√13)对称性的周期性。扫描隧道能谱分析结果表明，在裸露的SrTiO3(100)-(√13 ×√13)- r33.7°表面上形成了两种类型的缺陷，一种与缺陷具有相同的态密度，另一种具有窄带隙结构。这些结果归因于FeOx/SrTiO3(100)界面上二维空穴气体的形成。

Scanning tunneling microscopy observation of Fe deposited SrTiO3(100)-(√13 × √13)-R33.7° surface

Scanning tunneling microscopy imaging of Fe deposited SrTiO3(100)-(√13 × √13)-R33.7° surface is presented. Low-energy electron diffraction patterns showed that the surface reconstruction remained after Fe deposition at room temperature. Fe deposition generated defects, including oxygen vacancies, on the SrTiO3(100)-(√13 × √13)-R33.7° surface. These defects have a periodicity with the c(√13 × √13) symmetry. Scanning tunneling spectroscopy demonstrated the formation of two types of defects: one had the same density of state with defects on the bare SrTiO3(100)-(√13 × √13)-R33.7° surface, and the other had a narrow band gap structure. These results are attributed the formation of a two-dimensional hole gas at the FeOx/SrTiO3(100) interface.
