In this paper, we studied the early stage of growing silver monolayer on Cu(110) using kinetic Monte Carlo Method. In this investigation, we have considered atomic deposition, diffusion and aggregation. We have observed a transition from (1D) to (2D) geometry for temperatures beyond 280K. This transition is mainly due to several elementary processes such as simple atomic jump, detachment and coalescence of clusters. All activation energies have been previously calculated by the drag method in the framework of molecular dynamics simulations and implemented in the KMC code according to the anisotropic bond breaking model (ABBM). The potential adopted in molecular dynamics simulation is based on the embedded atom method. The analysis of kinetic Monte Carlo results allowed the collection of statistical information of adatom and cluster distribution. We also calculated two internal geometric parameters that characterize the evolution of the surface morphology. These calculations have been performed for various temperatures and adatom fluxes.
