Abstract

Energy- and structure-related properties of small gold clusters deposited on the GaAs(110) surface were investigated in this work using a molecular dynamics procedure. A recently developed potential energy function based on two- and three-body interactions was employed in calculating energies and forces. These calculations produced some consistent results with experiments. The three-body interactions involving As atoms in particular, were found to play an important role in determining favorable binding sites for deposited gold atoms.
