Abstract

We show that electron transport through a long multichannel wire, connected to leads by tunnel junctions, at low temperatures T and voltages V is dominated by inelastic cotunneling. This mechanism results in experimentally observed power-law dependence of conductance on T and V, in the diffusive regime where usual Coulomb anomaly theory leads to exponentially low conductance. The power-law exponent α* is proportional to the distance between contacts L.
