摘要：

Submonolayer epitaxy is studied with two simple theoretical models where adatom exchange with a surface atom yields a stable nucleus for island growth. The results are relevant to systems where surface layer inclusions are formed by alloying and where buried islands are formed in the presence of surfactants. Rate equations and Monte Carlo simulations are used to study the evolution of the island size distributions. The rate equations reproduce all of the qualitative features found in both the simulations and in recent experiments when the coverage-dependent rate of adatom capture by islands is calculated self-consistently.
