A solvable model for localized adsorption in a Coulomb system
Abstract
A model for an interface with localized adsorption is presented, in which the surface has a distribution of sticky adhesive sites in contact with a Coulomb fluid. Contrary to the current literature on the electrical double layer the surface charge is in dynamic equilibrium with the bulk fluid. The sum-rules obeyed by the one-and two-body correlation functions are investigated. Explicit results are obtained for a solvable model, the two dimensional one-component plasma at reduced temperature 2. The effect of the granularity of the adsorbed charge on the adsorption isotherm is discussed.
