Nanotechnology aids in cooling electrons without external sources

A team of researchers has discovered a way to cool electrons to -228 °C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy.

The process involves passing electrons through a quantum well to cool them and keep them from heating.

The team details its research in “Energy-filtered cold electron transport at room temperature,” which is published in Nature Communications on Wednesday, Sept. 10.
