Description

Highly asymmetric Josephson NbN-NbN*-Nb oxide-Pb junctions have been fabricated. A prominent feature, known as a 'knee', has been observed in the energy-gap region of quasiparticle current-voltage curves. It is discussed and explained within a conventional scattering approach to the phase-coherent charge transport in a quasiballistic double-barrier S1-I1-N-I2-S2 heterostructure with an extremely great difference between the two barrier transparencies
