A MonteCarlo simulations study has been performed in order to study theeffect of Pb as surfactant on the initial growth stage of Co/Cu(111). The maincharacteristics of Co growing over Cu(111) face, i.e. the decorated doublelayer steps, the multiple layer islands and the pools of vacancies, disappearwith the pre-evaporation of a Pb monolayer. Through MC simulations, a fullpicture of these complex processes is obtained. Co quickly diffuses through thePb monolayer exchanging place with Cu atoms at the substrate. The exchangeprocess diffusion inhibits the formation of pure Co islands, reducing thesurface stress and then the formation of multilayer islands and the pools ofvacancies. On the other hand, the random exchange also suppress the nucleationpreferential sites generated by Co atoms at Cu steps, responsible of the stepdecoration.Comment: 4 pages, latex, 2 figures embedded in the tex
