Resumen:
The diusion of a single dimer adsorbed on highly correlated heterogeneous substrates is
studied through Monte Carlo simulations. The topography has been characterized by patches
of weak and strong adsorbing sites, arranged in a chessboard-like ordered structure. The time
behavior of the mean-square displacement of the dimer is analyzed for dierent temperatures and
patch size. Based on this analysis, a possible method for the characterization of the correlated
heterogeneous topography from dimer diusion measurements is discussed.
