Abstract
We describe the gap voltage depression and current-voltage (I-V) characteri stics in pumped niobium superconductor-insulator-superconductor junction wi th niobium titanium nitride tuning stripline by introducing an electron hea ting power contribution resulting from the photon-assisted tunneling proces s. Theoretical fits using the extended Tien-Gordon theory are obtained that reproduce the most salient features of the pumped I-V characteristics. (C) 2001 American Institute of Physics.
