Abstract

The vertical growth of nanodimensional cobalt clusters buried under the surface of a gold substrate has been studied using computer simulation methods with allowance for the interdiffusion of Au and Co atoms and the fields of elastic stresses generated by cobalt clusters in the gold matrix. The temporal variation of the concentrations of Co and Au atoms in the near-surface layers is described and the characteristic times of gold replacement by cobalt in layers above the buried clusters are determined. The results of simulations are compared to the available experimental data.
