KINETICS OF INTERFACE GROWTH IN DRIVEN SYSTEMS

We study growing interfaces by the numerical simulation of several three-dimensional systems: the Kardar-Parisi-Zhang equation, a discrete variant of that model, and a solid-on-solid model with asymmetric rates of evaporation and condensation. Growth exponents in the rough phase are calculated, and we estimate the kinetic roughening transition temperature, its dependence on driving force, and analyze the transition by finite-size scaling. We find the transition depends strongly on driving force, which could be investigated experimentally. © 1990 The American Physical Society.
