Abstract: An investigation of the influence of the sizes of small Co clusters on the Cu(100) surface on the energy barriers of diffusion processes near the clusters and on their surface has been performed using a molecular statics method. The low-temperature mechanism of formation of empty zones near the cluster edges has been established.
