Temperature dependence of scaling laws in adsorption on bivariate surfaces

Abstract

The adsorption of particles with nearest-neighbor repulsive interactions is studied through Monte Carlo simulation on bivariate surfaces characterized by patches of weak and strong adsorbing sites of size l. Patches are considered to have a square geometry and they can be either arranged in a deterministic ordered structure or in a random way. Quantities are identified which scale obeying power laws as a function of the scale length l and its dependence on the temperature is determined. Consequences of this finding are discussed for the determination of the energetic topography of the surface from adsorption measurements.
