摘要：

We give a theoretical argument which indicates that the combined effect of substrate inhomogeneity and grain boundaries can be very important in determining the growth morphology of thin metal films on non-wetting substrates. An elongated metal island on a smooth non-wetting substrate, with a single grain boundary at its center, is shown to be in a state of unstable equilibrium. Any substrate inhomogeneity is then able to pin the island in a metastable state. An estimate of the depinning temperature is also given.
