通过反射高能电子衍射、X射线光电子能谱和X射线光电子衍射（XRD）研究了（111）CdTe表面。描述了几种表面重建。Cd（3d）结合能级的变化允许将表面Cd原子的贡献与体原子的贡献分开。虽然体原子表现出XPD效应沿着的标准晶体学方向，表面原子的衍射效应发生沿着不同的方向，对应于一个向外松弛的最顶部的Te层。这些发现与最近提出的CdTe（111）表面模型一致。
The (111) CdTe surface is studied by reflection high energy electron diffraction, x‐ray photoelectron spectroscopy, and x‐ray photoelectron diffraction (XRD). Several surface reconstructions are described. Shifts in the Cd (3d) binding energy levels allow separation of contribution of surface Cd atoms from that of the bulk. While bulk atoms exhibit XPD effects along the standard crystallographic directions, for surface atoms the diffraction effects occur along distinct directions which correspond to an outwards relaxation of the topmost Te layer. These findings are consistent with a recently proposed model of the CdTe (111) surface.
