Coulomb blockade of tunneling between disordered conductors - art. no. 126804

We determine the zero-bias anomaly of the conductance of tunnel junctions b y an approach unifying the conventional Coulomb blockade theory for ultrasm all junctions with the diffusive anomalies in disordered conductors. Both e lectron-electron interactions within the electrodes and electron-hole inter actions between the electrodes are taken into account nonperturbatively. Ex plicit results are given for one- and two-dimensional junctions, and the cr ossover to ultrasmall junctions is discussed.
