Percolation of binary mixtures adsorbed on square lattices

Abstract

In this paper, the adsorption of interacting binary mixtures on square lattices has been studied. By using Monte Carlo simulation and finite-size scaling analysis, the connection between the surface ordered phases and the percolating properties of the adsorbed phase has been investigated. A rich phase diagram separating a percolating from a nonpercolating region has been determined. The main features of the phase diagram have been discussed in terms of simple considerations related to the interactions present in the problem.
