Electric double layer of electrons: Attraction between two like-charged surfaces induced by Fermi–Dirac statistics

Publication date: Available online 6 November 2018Source: Physics Letters AAuthor(s): Mitja Drab, Veronika Kralj-IgličAbstractRecently we reported that Fermi–Dirac statistics of electrons contained between two oppositely charged surfaces separated by the order of nanometers create overlapping electric double layers with repulsive total force between the surfaces. Here, we present a new branch of solutions to the same variational problem resulting in higher energy densities and identify regions of the phase space where the force between two like-charged surfaces is attractive.
