Abstract: | In this note the method of Mott and Littleton is adopted to construct the position dependent correlation potential for energy bands in a non-metallic solid. One specifically studies the case of a solid with a surface. The principle result is that the effect of electronic correlation is to inhibit the effect of formation of true localized surface states in the region of the band gaps. |
