Abstract The structure of high Miller index Si(47 35 7) surface, inclined at 10.7° to the (1 1 0) plane is investigated using low energy electron diffraction, scanning tunneling microscopy (STM) and first principles calculations based on the density functional theory. It was shown that the surface has the 1 × 1 periodicity and is significantly reconstructed, exhibiting the pentameric structures similar to that found on Si(1 1 0) and Ge(1 1 0) surfaces. The tentative surface model is developed on the basis of high-resolution STM images and the universal building block structure recently proposed for Si(1 1 0) and Ge(1 1 0) reconstructed surfaces [Appl. Surf. Sci. 494 (2019) 46].

高米勒指数Si(47 35 7)表面的原子结构

摘要 利用低能电子衍射、扫描隧道显微镜 (STM) 和基于密度泛函的第一性原理计算，研究了高米勒指数 Si(47 35 7) 表面的结构，与 (1 1 0) 面成 10.7°。理论。结果表明，该表面具有 1 × 1 的周期性并且显着重建，表现出类似于在 Si(1 1 0) 和 Ge(1 1 0) 表面上发现的五聚体结构。暂定表面模型是在高分辨率 STM 图像和最近为 Si(1 1 0) 和 Ge(1 1 0) 重建表面提出的通用构建块结构的基础上开发的 [Appl. 冲浪。科学。494 (2019) 46]。
