Peltier effect in normal metal-insulator-heavy fermion metal junctions

摘要

A theoretical study has been undertaken of the Peltier effect in normal metal–insulator–heavy fermion metal junctions. The results indicate that, at temperatures below the Kondo temperature, such junctions can be used as electronic microrefrigerators to cool the normal metal electrode and are several times more efficient in cooling than the normal metal–heavy fermion metal junctions.
