Abstract

Thin films are usually thermodynamically unstable in the as deposited state due to their surface to volume aspect ratio. Heating can lead to fragmentation of a thin film and the formation of islands, which is called as solid-state dewetting for temperatures below the melting point. The process is driven by the minimization of the total energy of the system. In this talk, I will talk about how to use sharp-interface models for simulating solid-state dewetting problems. Taking the 2D case for example, I will explain the main idea behind these approaches; some extensions to the 3D case will be also presented.
