It has been found that a nucleated SMC perturbs the surface potential relief within a limited zone around itself in a way that some of the sites in the zone demonstrate a great preference for nucleating a new cluster, while in the other sites the nucleation is greatly suppressed. Outside the zone, the nucleation probability is close to that of the random nucleation simulated using Monte-Carlo technique. Energetic background of the observed phenomena has been proved using density-functional theory calculations, which clearly demonstrate that the lower the formation energy the higher the occurrence probability of a given cluster-pair configuration. © 2010 Elsevier B.V.
