Determination of the Thickness and Composition Profiles for a Film of Binary Mixture on a Solid Substrate

Abstract: Abstract. We determine the steady-state structures that result from liquid-liquid demixing in a free surface film of binary liquid on a solid substrate. The considered model corresponds to the static limit of the diffuse interface theory describing the phase separation process for a binary liquid (model-H), when supplemented by boundary conditions at the free surface and taking the influence of the solid substrate into account. The resulting variational problem is numerically solved employing a Finite Element … Show more

Equations of similar form may as well model the epitaxial evolution of surfaces of crystalline solids [38][39][40]2].…”
