A numerical study of the epitaxial growth of silver on silver (110)

The growth modes of the Ag(110) surface are studied near room temperature by means of Kinetic Monte Carlo simulations. For the elementary diffusion processes, we use energy barriers determined by quenched molecular dynamics simulations where silver has been modeled by many-body potentials. Numerical results show evidence of layer growth under Molecular Beam Epitaxy conditions. The island number density and the adatom density at small coverages display a power-law dependence on the diffusion length.
