摘要：

The nucleation and growth of two-dimensional islands on a vicinal substrate during the early stages of epitaxial growth is studied with kinetic Monte Carlo simulations and self-consistent rate equations. The island size distribution and island number density are shown to satisfy a dynamic crossover scaling form. A generalization of the self-consistent mean-field rate theory to vicinal substrates provides quantitative agreement with simulations.
