Resumen:
The adsorptiondesorption process occurring on heterogeneous surfaces is studied byconsidering a special case where a fractal is used as adsorbent. The fractal surface is thespanning cluster corresponding to the random deposition of objects that occupy morethan one site (k-mers) on a square lattice. Such a surface is characterized according tothe deposited k-mer. Then, the adsorption of repulsively interacting particles adsorbed onthe fractal surface is studied by using Monte Carlo simulations. Different thermodynamicquantities (adsorption isotherms, coverage susceptibility, etc.) are calculated and explainedin terms of the characteristics of the substrate. A scheme to characterize the structure ofthe substrate by just considering the adsorption isotherm is presented and discussed.
