Growth Morphology of Ag Islands on GaAs (110) at Low Coverage: Monte Carlo Simulations

  • Ashok Challa (a1), Timothy S. Cale (a2) and Jeff Drucker (a3)
Abstract

The growth morphology of Ag on GaAs (110) surface, at low coverage, is investigated with Monte Carlo simulations using a solid-on-solid model. Experimentally Ag deposited at room temperature forms isotropie islands and forms islands elongated along the <110> direction when deposited at 250°C. The preliminary results from our Monte Carlo simulations indicate that anisotropy in the surface migration and near-neighbor interactions are the main factors for the elongated islands observed for depositions performed at 250°C.
