摘要：

The result of investigation with the self-learning kinetic Monte Carlo method of processes, occurring during the formation of the Pt/Cu(111) surface alloy, is presented. A model is proposed that takes into account the jumps of dimers during the formation of a heterogeneous alloy on the (111) surface. The role of the diffusion of dimers at the temperature close to room temperature is investigated. The relative number of dimer jumps is calculated for the most significant stages of the Pt/Cu(111) alloy formation.
