Abstract

The aim of this paper is to study the diffusion of Cu adatom on Ag (110) by using the molecular dynamics simulation in the framework of the embedded atom method (EAM) as model of atomic interaction. Our simulation results predict that several diffusion processes such as simple jump, long jump and exchange mechanism may occur in the same system. The static barrier is calculated for each process by the drag method. The dynamic activation energy calculated from the Arrhenius law is in a good agreement with the static barrier. The presence of double jump is studied using velocity correlation function showing small contributions in diffusion process. Implications of these findings are discussed in more details.
