Electro-luminescent cooling: light emitting diodes above unity efficiency

Electro-luminescent cooling: light emitting diodes above unity efficiency

Experimental demonstration of net electro-luminescent cooling in a diode, or equivalently electroluminescence with wall-plug efficiency greater than unity, had eluded direct observation for more than five decades. We review experiments demonstrating light emission from a light-emitting diode in whic...
