Computer Simulation of Surface Damages at Atomic Scale Inducedby Cluster Impacting

A many-body hybrid potential, which is the combination of the tight-binding and the Moliere potential, has been developed. The surface damages at atomic scale caused by gold clusters, with energy of 3250eV, impacting on gold crystals have been investigated by molecular dynamics simulation. The results are compared with that from the two-body Moliere potential.
