Abstract
The diffusion of particles adsorbed on a patchwise surface with two non-equivalentsites is investigated in the framework of the lattice-gas model. The coverage dependencies of thecenter-of-mass and Fickian diffusion coefficients are calculated for some representative valuesof the lateral interaction. We propose the analytical expressions for the diffusion coefficients.We compare the theoretical dependencies with the numerical data obtained by the kineticMonte Carlo simulations. The good coincidence of the data obtained by the two quite differentmethods corroborates strongly the approach developed to describe the particle migration onsuch complex, heterogeneous lattices.
