Cooper pair cotunneling in single charge transistors with dissipative electromagnetic environment
arXiv:cond-mat/0305113 · doi:10.1103/PhysRevLett.91.197002
Abstract
We observed current-voltage characteristics of superconducting single charge transistors with on-chip resistors of R about R_Q = h/4e^2 = 6.45 kOhm, which are explained in terms of Cooper-pair cotunneling. Both the effective strength of Josephson coupling and the cotunneling current are modulated by the gate-induced charge on the transistor island. For increasing values of the resistance R we found the Cooper pair current at small transport voltages to be dramatically suppressed.
