    The growth morphology of Ag on GaAs (110) surfaces, at low coverages, is investigated with Monte Carlo simulations using a solid-on-solid model. Experimentally Ag deposited at room temperature forms 3D isotropic islands and forms needle-like islands elongated along the 〈110〉 direction when deposited at 250°C. Preliminary simulation results using 2D island growth model indicated that the elongation of islands at 250°C deposition is due to anisotropic surface diffusion and nearest-neighbor interactions along the 〈100〉 and 〈110〉 directions. The island morphologies obtained using a 3D island growth model are in good agreement with experimentally observed morphologies.
