Resumen:
The behavior of the surface diffusion coefficient on an heterogeneous correlated surface is studied in the framework of the lattice-gas model. Using the multivariate adsorptive energy distribution function the statistical properties of the heterogeneous correlated surface can be appropriately described an the effect of the heterogeneity on the collective diffusion coefficient at finite coverage can be analyzed through a correlation length. Monte Carlo simulation s also performed to test the analytical results.
