Dewetting of Thin Solid Films
The dewetting of epitaxial thin films of solid deposited on substrates occurs in microelectronic and optoelectronic devices. Dewetting can occur when an initially planar thin film forms a hole exposing the substrate. This hole grows via mass flow along the surface of the film. The morphological stability of the dewetting film is not well understood. The speakers in this minisymposium will present recent numerical, analytical and experimental work. They will discuss the effects of capillarity, elasticity, thermodynamics, anisotropy and contact-angle dynamics on the morphological evolution of the film and the formation of island shapes, cracks, and dislocations.
