Percolation of dimers irreversibly adsorbed on heterogeneous surfaces
The percolation problem of irreversibly deposited dimers on square lattices with two kinds of sites is studied. Simple adsorptive surfaces are generated by square patches of l x l sites, which can be either arranged in a deterministic chessboard structure or in a random way. Thus, the system can be...

| Sumario: | The percolation problem of irreversibly deposited dimers on square lattices with two kinds of sites is studied. Simple adsorptive surfaces are generated by square patches of l x l sites, which can be either arranged in a deterministic chessboard structure or in a random way. Thus, the system can be characterized by the distribution (ordered or random) of the patches, the patch size l and the probability of occupying each patch θi (i = 1, 2). Dimers (particles that occupy two neighboring sites simultaneously) are irreversibly adsorbed on the lattice. By means of random adsorption simulations and finite-size scaling analysis, a complete (θ1-θ2-l) phase diagram separating a percolating and a non-percolating region is determined. |
