KINETICS OF RESTRICTED SOLID-ON-SOLID MODELS OF FILM GROWTH

We consider the kinetics of irreversible film growth in solid-on-solid models with various restrictions on the adsorption (or growth) sites. We show how the master equations for the probabilities of subconfigur ations of filled sites can be analyzed exactly to obtain coverages and spatial correlations for the first several layers. These provide an e fficient framework for analysis of the early-stage growth kinetics, an d indicate rapid attainment of asymptotic behavior. We illustrate the (1+1)- and (2+1)-dimensional cases for the simplest restricted solid-o n-solid condition, and various modifications.
