摘要：
A model with deposition, diffusion, and reversible aggregation on a two-dimensional rectangular lattice with both anisotropic diffusion barriers and anisotropic nearest-neighbor bonds is studied by kinetic Monte Carlo simulations. The model is applied to the case of Ag growth on Ag(110). The barriers for the elementary processes are calculated by many-body tight-binding potentials. At fixed T decreasing the Bur (or at fixed Bur and increasing T), the model displays morphology changes from small isotropic aggregates to one-dimensional strips and then to two-dimensional islands.
