title: The study of percolation with the presence of impurities.
abstract: We consider the process of percolation cluster formation for point-like conductors subjected to random sequential adsorption onto two-dimensional lattice by computer Monte Carlo simulations. The initial presence of impurities disturbs this phenomenon significantly and we study here how the size and density of impurity particles affect the resulting percolation threshold. Some unexpected features such as the nonmonotonicity of the percolation threshold as a function of impurity concentration are discussed.
