Abstract

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.
