The first physical GELATO meeting has been held in Marseille the 24th and 25th of November 2022. We had the chance to welcome all the GELATO partners. In particular, Prof.…

Based on full quantum-transport simulations, we report a comprehensive study of the evaporative cooling process in a double-barrier semiconductor heterostructure thermionic refrigerator. Our model, which self-consistently solves the nonequilibrium Green’s function framework and the heat equation, is…

We investigate electron transport in asymmetric double-barrier AlGaAs/GaAs thermionic cooling heterostructures (Fig.1). Measurements of temperature-dependent current-voltage characteristics confirm that the dominant electron trans
