New Polariton Refrigeration Technique Provides New Way to Cool Electronic Devices

Polariton refrigerator could chill tiny semiconductor devices Physics World, May 15, 2015. Image credit: geralt A new method for using light to cool solids has been created by physicists in France and Germany. The technique uses quasiparticles called “polaritons” to remove vibrational heat from a tiny piece of semiconductor, and unlike previous optical cooling schemes […]
