Resumen:
Adsorption and collective diffusion of interacting particles on one-dimensional heterogeneous substrates are studied by Monte Carlo (MC) simulation. The collective diffusion coefficient is determined by employing the Kubo-Green theory, through the jump diffusion coefficient and the thermodynamic factor. The correlated heterogeneous substrate is generated through the Dual Site-bond Model, considering two limit topographies: random and high correlated surface topographies. A rich variety of different behaviors is found and analyzed in the framework of the lattice gas model.
