Abstract
Computer simulation of tunnelling into materials with a Coulomb gap is presented. The model system is a three-dimensional Coulomb glass lyin g to one side of an infinite plane. An equipotential near the plane si mulates the electrode, which screens the Coulomb interaction between l ocalized electrons in the Coulomb glass. The depth-dependent one-parti cle density of states is computed, and the results are then used to ob tain the tunnelling conductance of the system as a function of voltage .
