title: Anisotropy and coarsening in the instability of solid dewetting fronts.
abstract: We report on the destabilization of the film edge during the dewetting of ultrathin solid films. An unusual coarsening behavior is found within the linear instability regime. In addition, we find that the instability is suppressed along faceted orientations. Our results are obtained via kinetic Monte Carlo simulations. An analytical model based on diffusion-limited mass transport on the rim and nucleation-limited increase of the rim height provides a good description of kinetic Monte Carlo simulations. Our results are consistent with recent experimental observations.
