Abstract

When polycrystalline films form by nucleation, growth, impingement, and coalescence of islands on a substrate surface, the grain size at impingement depends on the relative magnitudes of the nucleation rate, the growth rate, and the dimension of the zone from which adatoms diffuse to a growing island. A simple description of the interdependence of these parameters is developed. It is used to discuss the dependence of the grain-size-at-impingement and the intrinsic stress resulting from coalescence on the deposition rate and the substrate temperature, and to discuss how these might affect texture evolution during film growth.
