摘要: Publisher Summary This chapter discusses the growth mechanism and structures formed in a model system involving fee metal deposited onto bcc substrate at low coverages. The goal is to discern structure of film as it begins grow understand physical reasons for type observed. describes sub-monolayer regime study island lattice-mismatched interface. These islands will ultimately determine structural fate interface, that is, whether be smooth or rough, commensurate incommensurate, ordered disordered. In coverages, adlayer found pseudomorphically, both experimentally theoretically. results from potential energy corrugation induced by substrate. pseudomorphic growth, however, induces an internal strain within affects its subsequent preferences. No additional information about microscopic submonolayer has been obtained experiments; calculations presented are designed provide more detailed view mechanisms.
