Abstract

We consider the instabilities of a solid film perturbed by a single hole which exposes the substrate. We predict growth for holes larger than a critical size, proportional to the ratio of the film thickness and the equilibrium contact angle. The asymptotic velocity of the hole decays to zero with time t as t^¾ [log³ (t/ρ_c⁴)]. The growth of these holes eventually ruptures the film, creating a set of disconnected islands.
