Recombination limited energy relaxation in a BCS superconductor
A. V. Timofeev, C. Pascual Garcia, N. B. Kopnin +4
We study quasiparticle energy relaxation at sub-kelvin temperatures by injecting hot electrons into an aluminium island and measuring the energy flux from electrons into phonons bo…
Heat Transistor: Demonstration of Gate-Controlled Electron Refrigeration
Olli-Pentti Saira, Matthias Meschke, Francesco Giazotto +3
We present experiments on a superconductor-normal metal electron refrigerator in a regime where single-electron charging effects are significant. The system functions as a heat tra…
Opportunities for mesoscopics in thermometry and refrigeration: Physics and applications
Francesco Giazotto, Tero T. Heikkila, Arttu Luukanen +2
This review presents an overview of the thermal properties of mesoscopic structures. The discussion is based on the concept of electron energy distribution, and, in particular, on…
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…
