Cold electron Josephson transistor
A. M. Savin, J. P. Pekola, J. T. Flyktman +2
A superconductor-normal metal-superconductor mesoscopic Josephson junction has been realized in which the critical current is tuned through normal current injection using a symmetr…

Limitations in cooling electrons by normal metal - superconductor tunnel junctions
J. P. Pekola, T. T. Heikkila, A. M. Savin +3
We demonstrate both theoretically and experimentally two limiting factors in cooling electrons using biased tunnel junctions to extract heat from a normal metal into a superconduct…
