A kinetic Monte Carlo (kMC) simulation is conducted to study the growth of ultra-thin film of Co on Cu(001) surface.The many-body,tight-binding potential model is used in thesimulation to represent the interatomic potential.The film morphology of heteroepitaxial Co filmon a Cu(001) substrate at the transient and final state conditions with various incident energiesis simulated.The Co covered area and the thickness of the film growth of the first two layers areinvestigated.The simulation results show that the incident energy influences the film growth andstructure.There exists a transition energy where the interfacial roughness is minimum.There aresome void regions in the film in the final state,because of the influence of the island growth in thefirst few layers.In addition,there are deviations from ideal layer-by-layer growth at a coveragefrom 0～2 monolayers (ML).
