Abstract

The structure of a model liquid crystalline fluid confined between two microstructured substrates is studied through Monte Carlo simulations. A simple model for a structured substrate, similar in spirit to those used for rough walls of walls with grafted polymers, is introduced. It is found that varying the structure of the substrate, a transition in the alignment of the confined fluid, from parallel to perpendicular, is induced. For particular substrate structures, it is possible to induce tilted alignment in the confined fluid, the tilt angle being temperature dependent.
