| Abstract(in English) | We experimentally demonstrate Cooper-pair's drastic enhancement of band-to-band radiative recombination rate in a semiconductor. Electron Cooper-pairs injected from a superconducting electrode into an active layer by the proximity effect recombine with holes injected from a p-type electrode. The recombination of a Cooper-pair with p-type carriers dramatically increases the photon generation probability of a light emitting diode in the optical-fiber communication band. The measured radiative recombination lifetime rapidly decreases with decreasing temperature below the superconducting transition temperature of niobium electrodes. Our results indicate the possibility to open up new interdisciplinary fields between superconductivity and optoelectronics. |
