Diffusion of Ag, Sn, and Pb over Atomically Clean Ge(111) Surface

Auger electron spectroscopy and low-energy electron diffraction were used to study the diffusion of Ag, Sn, and Pb over the Ge (111) surface. The mechanisms of diffusion of atoms of these elements over the Ge(111) surface are determined, and the temperature dependences of the diffusion coefficients are measured. The parameters of diffusion of these elements over the Ge(111) and Si (111) surfaces are compared.
