Comparative study of heat-driven and power-driven refrigerators with Coulomb-coupled quantum dots

Résumé

Multiterminal multidot devices have been put forward as versatile and high-performing setups for thermoelectric energy harvesting at the nanoscale. With a technique that encompasses and overtakes several of the usual theoretical tools used in this context, we explore a three-terminal Coulomb-coupled-dot device for refrigeration purposes. The refrigerator is monitored by either a voltage or a thermal bias. This comparative study shows that the heat-driven refrigerator is underperforming relative to the power-driven one, due to scarce on-dot charge fluctuations.
