The tiniest refrigerator in the world

Abstract:
A Finnish group of researchers at the Low Temperature Laboratory of Helsinki University of Technology (TKK) have developed and fabricated a nanoscale heat transistor, and simultaneously the smallest refrigerator ever made. The device, nanofabricated with the help of electron beam lithography, functions at extremely low temperatures of less than one degree above absolute zero. The possibility to control the electrons going through the device one by one in the metal-superconductor structure enables its use as a heat transistor.
