Abstract
A model for the growth of Ag on Ag(110) at submonolayer coverages is presented. The model includes deposition, diffusion and fully reversible aggregation with anisotropic diffusion barriers and nearest-neighbour bonds. The barriers for the elementary processes are calculated by many-body tight-binding potentials. Depending on growth parameters, different island morphologies are obtained. At low temperatures, small irregular clusters grow. In the intermediate regime, long monatomic strips in the in-channel direction are found. At high temperatures, large two-dimensional compact clusters are obtained.
