Patent US 20100019618 (US Patent Office, Jan. 28 2010)
A semiconductor device for the environment heat conversion in coherent electromagnetic energy by a super radiant quantum decay and a thermal excitation of a system of electrons in a super lattice of n-i-p-n transistors with quantum dots on the two sides of the i-layer, and potential barriers for separating the quantum transition n-i-p regions from the adjacent conduction n and p regions. When an electron current is injected in a perpendicular direction on the transistor arrays, a super radiant field is generated in the plane of these arrays, with a power mainly obtained by a heat absorption that is much larger than the absorbed electric power. The device also includes an input heat absorber, and an output Fabry-Perot resonator with total transmission for the electromagnetic energy extraction from the device active region.
