Random sequential adsorption on a triangular lattice

Abstract

Random sequential adsorption of objects of various shapes on a planar triangular lattice is studied by Monte Carlo simulation. Various shapes are made by self-avoiding random walks on the lattice. At the late stage of deposition, the approach to the jamming coverage is exponential for all shapes and of the same form as for the square lattice. Jamming configurations consist of clusters of blocked sites and domains of parallel deposited objects. The jamming coverage decays exponentially with the size $s$ of the deposited objects. For the deposition of mixtures the jamming coverage increases with the number of components in the mixture.
