Superconductive tunneling in junctions with resonant double barrier structures

We calculate the current-voltage characteristics (IVC) of a biased superconducting junction with a tunnel resonance. Within a simple one-dimensional model we discuss how the IVCs depend on the position and width of the resonance. We consider both subgap region and excess current. The results provide a possible explanation of the anomaly in the onset of c-axis current in recent experiments on intrinsic Josephson effect in BSCCO. (C) 1997 Elsevier Science B.V.
