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.
