| Abstract: | In the range of tunnel resonance energies of a disordered N-I-N (N is a normal metal, I is an insulator) contact, its tunnel conductance is represented as the sum over the quantum resonance-percolation trajectories that are randomly formed in the disordered I layer and connect the opposite junction edges 1]. Such a representation made it possible to obtain a formula for the mesoscopic conductance fluctuations, on the basis of which the self-averaging criterion was derived. |
