摘要：
The Josephson-quasiparticle (JQP) current cycle in the superconducting single-electron transistor (SET) involves both resonant Cooper-pair and quasiparticle-tunneling. We have measured the JQP current cycle for SETs with the charging energy E-c ranging from 0.6 to 1.1 Delta (the superconducting energy gap). We find this cycle can be quantitatively modeled by a theory of Averin and Aleshkin that treats the Cooper-pair tunneling rate as Lorentzian. (C) 2000 Elsevier Science B.V. All rights reserved.
