Simulations of Island Growth and Island Spatial Distribution during Electrodeposition

摘要

Recently we have developed a kinetic Monte Carlo model of nucleation and island growth during bulk electrodeposition. In this article we report on the growth rate of individual islands and the spatial distribution of islands on the surface. The growth curves of individual islands show two power law regimes with exponents of 1/2 and 1/6, respectively, and we show that the time associated with the transition between the two regimes is dependent on the local environment. We also show that ion depletion in the vicinity of a growing island increases the spatial ordering of the island distribution.
