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 pha...

Description
Summary: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. •Percolation properties of equilibrium adsorbed phases.•Interacting binary mixtures adsorbed on square lattices.•A rich variety of structural orderings were observed in the adlayer.•Percolation thresholds and percolation phase diagrams were obtained.
