Prewetting boundary tensions from Monte Carlo simulation.
We examine the boundary tension of a model system along the prewetting saturation line. Boundary tensions are evaluated through a combination of finite-size scaling and grand canonical Monte Carlo simulation. The model system consists of Lennard-Jones particles interacting with a single structureless surface. After scaling our dimensionless results with a characteristic force, we obtain a value of 2 x 10(-11) N for the boundary tension at the system's wetting temperature. This estimate is consistent with theoretical and recent experimental values.
