摘要

利用俄歇电子能谱和低能电子衍射研究了Ag和Pb在Ge(111)-3x2sqrt(3)sqrtSn表面的扩散。确定了这些元素原子沿Ge(111)-3x2sqrt(3)sqrtSn表面扩散的机理，并测量了扩散系数的温度依赖性。比较了Ag沿Ge(111)-3x2sqrt(3)sqrtSn和Si(111)-2sqrt(3)sqrtSn表面的扩散参数。关键词:表面，表面扩散，Ge(111)， Ag, Pb, Sn。

Ag and Pb diffusion on Ge(111)-3x2sqrt(3)sqrtSn surface

Ag and Pb diffusion on Ge(111)-3x2sqrt(3)sqrtSn surface has been studied by Auger electron spectroscopy and low energy electron diffraction. The mechanism of diffusion of atoms of these elements along the Ge(111)-3x2sqrt(3)sqrtSn surface is determined, and the temperature dependences of the diffusion coefficients are measured. The diffusion parameters of Ag along the Ge(111)-3x2sqrt(3)sqrtSn and Si(111)-2sqrt(3)sqrtSn surfaces are compared. Keywords: surface, surface diffusion, Ge(111), Ag, Pb, Sn.
