Keeping cool with quantum wells
(PHYSorg.com Physics)

University of Tokyo researchers have announced a new approach for electrical cooling without the need for moving parts. By applying a bias voltage to quantum wells made of the semiconductor aluminum gallium arsenide, electrons can be made to shed some of their heat in a process called `evaporative cooling.` Devices based on this principle may be added to electronic circuit boards using conventional semiconductor fabrication methods to help smartphones and laptops avoid performance issues caused by high temperatures.
