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…
