Abstract

We present molecular dynamics results on the diffusion properties of Ag monomers and dimers on the (111) surface of Pt. In particular we focus on the behavior of dimers upon collision on the surface with impact energies of 0.5eV and 5eV. We found that the dimer has the largest probability of being found stable on the surface when the temperature is in the range 150K<T<300K, while at T=OK a metastable configuration featuring monomers and dimers is likely to form.
