T. Biben et al., GENERIC DENSITY-FUNCTIONAL FOR ELECTRIC DOUBLE-LAYERS IN A MOLECULAR-SOLVENT, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 57(4), 1998, pp. 3727-3730
A simple, generic density functional for a statistical description of
electric double layers in a molecular solvent is presented. The functi
onal, which may be adapted to any geometry, is applied to the case of
planar geometry, to pinpoint the limitations of the usual continuum de
scription of the solvent.
