We apply a recently developed combined molecular dynamics–local Langevin equation method to the simulation of the scattering of Ar by the (100) face of a face-centered cubic solid. The kinetic energies of the Ar are chosen to be low compared to the typical energies used in sputtering. We find that even at low energies, a significant amount of surface damage is inflicted by the Ar, leading to ejection of metal atoms into the gas phase, the formation of dislocations, and the production of isolated atoms trapped on the surface. We study both the probability that such events occur and individual trajectories which display the dynamic processes through which sputtering takes place or defects are created.
