Percolation of binary mixtures adsorbed on square lattices

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 non-percolating 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.
