Resumen:
The equilibrium and transport properties of interacting ad-particles on bivariate heterogeneous chains are studied by combining analytical
and simulation approaches. Heterogeneity is introduced in the way of patches of shallow and deep adsorbing sites distributed in a
deterministic alternating way. Adsorption isotherms and mean-square fluctuations of the surface coverage, as well as the jump and collective
diffusion coefficients, are calculated for different values of lateral interactions between ad-particles and substrate heterogeneity. In
addition, different elementary jump mechanisms are introduced and their influence in the coverage dependence of the collective diffusion
coefficient is investigated.
