Abstract
We have studied numerically the density of states of one-dimensional and two-dimensional systems with localized states interacting via the electronectron Coulomb interaction. The results can explain tunnelling conductance measurements on granular A1 wires and films in terms of the Coulomb gap. We have considered the effects of a finite localization length, and of screening by a metallic electrode, on the Coulomb gap.Keywords
