Abstract

Simple physical arguments that explain the nature and limitations of charge inversion in a system where no interactions are operational except for the Coulomb and short-range hard core repulsion are presented. It is demonstrated that even spherical Z-ions adsorbed on a large plane macroion can lead to charge inversion larger than 100%, while for rodlike Z-ions charge inversion can even be larger.
