Phase diversity in an adsorption model of an additive binary gas mixture for all sets of lateral interactions

Abstract

Complete analysis of phase behavior of an adsorption model of a binary gas mixture on a square lattice was carried out for all possible sets of lateral interactions between nearest adsorbed molecules of the same type and no interaction between adsorbed molecules of different types. The model was completely investigated in the ground state, and it was shown that the phase behavior of the system is conserved at finite temperatures by means of a transfer matrix method.
