Phys. Rev. B 76, 115429 (2007) [6 pages]Adsorption potentials for nonplanar geometriesReceived 2 May 2007; revised 12 July 2007; published 21 September 2007 We present a method to compute, assuming a continuous distribution of sources, the elementary potential created by a differential element of volume of matter, whose integral generates a known adsorption field V(z) for a planar surface. We show that this elementary potential is univocally determined by the original field and can be used to generate adsorption potentials for other nontrivial geometries. We illustrate the method for the Chizmeshya-Cole-Zaremba physisorption potential and discuss several examples and applications. © 2007 The American Physical Society URL:
