| Structure of a model liquid in contact with a nano-corrugated wall is studied using a free energy functional based on fundamental measure theory. Particles in the liquid interact via a potential which has a hard core repulsion and a short range attractive tail of Lennard-Jones type. The later part of interaction is treated by functional perturbation expansion.The liquid-wall interaction is characterized by a hard core repulsion followed by a van der Waal attraction. Corrugated surfaces are modeled by a periodic array of holes, slits and posts. Three dimensional density profiles are calculated for different geometries for varying inter-particle and wall-liquid interaction strength. |
