Abstract

We have investigated Josephson-quasiparticle (JQP) current in superconducting single-electron transistors in which charging energy EC was larger than superconducting gap energy Δ and junction resistances were much larger than RQ≡h/4e2. We found that not only the shapes of the JQP peaks but also their absolute height were reproduced quantitatively with a theory by Averin and Aleshkin using a Josephson energy of Ambegaokar-Baratoff’s value. © 1996 The American Physical Society.
