EFFECTS OF ATOMIC INTERACTIONS IN TWO-COMPONENT SUBMONOLAYER GROWTH

摘要

We discuss the effects of different chemical bondings on the island morphology and on the island density scaling in two-component sub-monolayer growth. Different regimes, depending on the strength of the mutual interactions and on the relative mobility of species, are described and studied with kinetic Monte Carlo simulations using a two-component solid-on-solid growth model. Results for the temperature and flux dependence of the island density as well as examples of the surface morphologies are presented.
