GROWTH OF AN ANISOTROPIC SURFACE: THE CASE OF AG/AG(110)

摘要

A growth model of Ag on Ag(001), incorporating anisotropic diffusion, bonding and Ehrlich-Schwoebel barriers, is developed and studied by kinetic Monte Carlo simulations. The model displays islands and ripples rotation in the submonolayer and multilayer regimes, respectively, in quantitative agreement with the experimental results. Moreover, the model allows the singling out of the key microscopic mechanisms underlying the phenomenology.
