Abstract

Metal heteroepitaxy was addressed by employing density-functional theory (DFT) to characterize the major rate processes. The aim was to achieve microscopic understanding of the island densities developing in the initial growth of Co on Cu(001), as well as their scaling behavior. A pronounced deviation from the typical Arrhenius behavior of island growth was found. A complex N-shape dependence of the island density on temperature was predicted theoretically and confirmed in an ion scattering experiment for Co on Cu(001).
