Density-Functional Theory of Nematics Near Surfaces
A density-functional theory for the growth of a nematic wetting layer near surfaces is presented. The theory predicts complete wetting at a high enough value of the surface field. The phenomenon is examined for p-azoxyanisole (PAA) in the framework of random-phase approximation (RPA).
