Low-temperature physics: Tunnelling into the chill
Jukka Pekola1
Abstract
The trend towards ever smaller electronic instruments had left refrigerators out in the cold. Now a practical, compact device uses quantum mechanical tunnelling to cool close to absolute zero.
The French physicist Jean Peltier discovered in 1834 that when an electrical current is passed through a solid-state circuit, heat is in some cases removed. Yet one obvious application, a solid-state micro-refrigerator capable of cooling to cryogenic millikelvin temperatures, has remained science fiction.
