View the Complete Application at the US Patent & Trademark Office
Solid state near-field radiative cooling from a cold emitter to a hot collector is provided. Two cases are considered. In the first case, the cold emitter is forward biased to drive heat flow from the cold emitter to the hot collector. A surface resonance of the collector is configured to enhance this cooling effect. In the second case, the hot collector is reverse biased to control heat flow from the cold emitter to the hot collector. A surface resonance of the emitter is configured to enhance this cooling effect.
