Impact of composition of extended objects on percolation on a lattice.
We consider the percolation aspect of random sequential adsorption of extended particles onto a two-dimensional lattice using computer Monte Carlo simulations. We investigate how the composition of the particles influences the value of the percolation threshold. Two regimes can be distinguished: one for almost linear particles (with the composition of straight segments reaching 85-100 %) and the second one for more bent (flexible) ones. For more bent particles we found a high correlation between the percolation threshold and the structure of an adsorbate at percolation. We also observe that there is no difference in the conclusions for both kinds of lattice considered (square and triangular).
