Evaporative electron cooling in asymmetric double barrier semiconductor heterostructures

Designing efficient integrated cooling solutions by controlling heat management in nanodevices remains a challenge. Here, the authors propose evaporative electron cooling in the AlGaAs/GaAs double barrier heterostructures quantum well achieving up to 50 K electron temperature reduction at 300 K.
