| Popis: | 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 Ec ranging from 0.6 to 1.1 Δ (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. |
