Abstract

The structure and dynamics of Cu(100), Cu(110) and Cu(111) have been studied by Molecular Dynamics simulations using the potential derived from effective medium theory. The formation energy for adatoms is lower for Cu(llO) than for Cu(lO0) or Cu(lll). The relatively high concentration of defects on Cu(11O) makes this surface premelt near the bulk melting point. The surface diffusivity is high for all three surfaces at elevated temperatures, the diffusion mechanism at the disordered surfaces appears to be quite complicated.
