Autor: Aymen Yangui, Marc Bescond, Tifei Yan, Naomi Nagai, Kazuhiko Hirakawa

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-7 (2019)

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

Rapid progress in high-speed, densely packed electronic/photonic devices has brought unprecedented benefits to our society. However, this technology trend has in reverse led to a tremendous increase in heat dissipation, which degrades device performa
