In the present paper, patterns of diffusion-limited aggregation (DLA) grown on nonuniform substrates are investigated by means of Monte Carlo simulations. We consider a nonuniform substrate as the largest percolation cluster of dropped particles with different structures and forms that occupy...

Grand canonical Monte Carlo simulations have been performed in order to study adsorption thermodynamics of pairwise interacting particles on fractal surfaces. Diffusion-limited aggregates (DLA) have been used as a substrate where interacting particles are adsorbed. In order to obtain aggregates...

Tracer and collective diffusion of repulsively interacting particles adsorbed on a random AB alloy surface (Nieto, Uebing, Eur. Phys. J. B 1 (1998) 523) are studied by means of Monte Carlo modelling. Adsorption isotherms and the thermodynamic factors are obtained via simulations in the...
