Circular nucleated holes develop upon dewetting in thick films, and they grow uniformly with time until coalescence with neighbouring holes occurs. Their growth rate follows a model that includes viscous dissipation in the rim and slippage on the substrate. Under certain conditions, however, nucleated holes in very thin films grow uniformly only up to a certain threshold value, beyond which a cascade pattern called "satellite holes" is observed. This pattern is the result of the interplay between the disjoining and Laplace pressure.Keywords: Atomic force microscopy; Coalescence; Dynamics; Energy dissipation; Heat treatment; Laplace transforms; Lubricants; Polystyrenes; Stiction; Thin films; Viscous flow; Wetting; Dewetting; Nucleated holes; Satellite holes; Structure formation; Thin polymer f AFM; Dewetting; Structure formation; Thin polymer filmsDynamics of Hole Growth in Dewetting Polystyrene Films200410.1016/j.physa.2004.03.0492015-12-11
