We have investigated both theoretically and experimentally the two-particle structures, which appear at low temperature in high quality Nb/A1Ox/Nb Josephson tunnel junctions in the subgap region of the current-voltage characteristics. We performed measurements on low Josephson critical current densi
The conductance-voltage characteristics of different types of Josephson tunnel junctions have been measured at 4.2 K: symmetric Nb/AI , AlOx/AI/Nb, asymmetric Nb/AI,AIOx/Nb and Nb/AI/AlO x -/AlOx/Nb, containing a double oxidation layer. The symmetric junctions can be described very well by a trapezo
