Abstract

A negative electroluminescent cooling device including a first layer of material; a second layer of material arranged at a non-zero distance from the first layer of material with help of a set of supporters, and an energy source to apply a reverse bias voltage to the first layer of material to cool the second layer of material. The material of the first layer is a semiconductor with a bandgap less or equal to a surface resonant energy of the second layer of material.
