Abstract

The current-voltage characteristics of Au/InO_x/Pb tunnel junctions exhibit peculiar zero-bias anomalies. At low temperatures the zero-bias resistance attains saturation values that are smaller than the normal-state resistance by a factor that often exceeds 2. This zero-bias anomaly (ZBA) is also characterized by voltage δ≤Δ, where Δ is the energy gap of lead. δ depends on the thickness of the InO_x layer. In the presence of a microwave field the ZBA features are affected in a nontrivial way. The possibility that these features arise from the nature of the barrier being an Anderson insulator is discussed.
