Surface, Defects, Atom Transport and Epitaxial Growth

该项目涉及结构缺陷的表征， 晶体，以及调查的作用，这些缺陷， 表面原子扩散 原子运动的机制 表面产生形态变化和表面相 将研究转型。 主要实验方法 结构和动力学研究将是扫描隧道 显微镜、低能电子衍射和表面x射线 衍射法 实验将在半导体上进行 （硅、锗和砷化镓）和金属单 晶体

This project involves characterization of structural defects on crystals, as well as investigations of the role of these defects in surface atomic diffusion. The mechanisms by which atoms move on surfaces to produce morphology changes and surface phase transitions will be studied. The major experimental methods for the structural and kinetic studies will be scanning tunneling microscopy, low energy electron diffraction, and surface x-ray diffraction. Experiments will be performed on semiconductors (silicon, germanium and gallium arsenide) and on metal single crystals.
