Диффузия Ag и Pb по поверхности Ge(111)-3x2sqrt(3)sqrtSn

Abstract

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