Description

The random motion of the particles in a two-species system in the presence of an external field, originally proposed as a model of certain kinds of materials known as superionic conductors, fast ion conductors, super ionic solids, or solid electrolytes, shows rather interesting steady-state, non-equilibrium behavior. In this “driven diffusive” system, the external field biases the movement of each species in opposite directions, and an order-disorder transition occurs as a function of density. We develop here a CA model of the driven diffusion of two species.
