摘要：
The cooperative sequential adsorption of dimers and trimers on heterogeneous substrates with random and patchwise (chessboard and strip) topographies is studied by Monte Carlo simulation. Strong influence of the topography is found on the adsorption kinetics, measured through the dependence of the sticking coefficient with the surface coverage, and the jamming coverage. In particular, an unexpected behavior of the jamming coverage is found for dimers and trimers on a random topography, which, unlike the case of dimers in one dimension, differs from that corresponding to a homogeneous surface.
