title: Dewetting of solid films with substrate-mediated evaporation.
abstract: The dewetting dynamics of an ultrathin film is studied in the presence of evaporation-or reaction-of adatoms on the substrate. KMC simulations are in good agreement with an analytical model with diffusion, rim facetting, and substrate sublimation. As sublimation is increased, we find a transition from the usual dewetting regime where the front slows down with time, to a sublimation-controlled regime where the front velocity is approximately constant. The rim width exhibits an unexpected nonmonotonous behavior, with a maximum in time.
