Abstract

Self-organized nanostructures obtained through capillarity effects are modeled and studied by Monte-Carlo type computer simulations. We focus on two practically important systems, recently studied by experimentalist groups. The first system is a polysterene nanosphere suspension drying on a silica substrate. The second one is formed in a system of drying vertically aligned nanotube-array. For modeling these experimentally obtained and fascinating nano-patterns, spring-block type models are used. Stochastic simulations performed on these models reproduce qualitatively the experimentally obtained structures and gives thus a promising description for the pattern formation dynamics..

Keywords
