Yn. Ovchinnikov et A. Schmid, RESONANCE PHENOMENON IN CURRENT-VOLTAGE CHARACTERISTIC OF THE JOSEPHSON-JUNCTION, Physica. B, Condensed matter, 194, 1994, pp. 1473-1474
Sharp peaks appear in I-V characteristic of the Josephson Junction whe
n levels in neighboring wells are crossing. The shape and size of thes
e peaks strongly depend on the parameters of the junction as well as o
n temperature and number of levels lying below the resonance one.
