SEMICONDUCTOR DEVICE FOR PRODUCING RADIATION IN RESPONSE TO INCIDENT RADIATION

摘要

A semiconductor device for producing radiation in response to incident radiation of wavelength is made of a sandwich of semiconductor materials providing electrically in series a radiation detector which responds electrically to incident radiation, a capacitor for integrating the effect of the incident radiation and a radiation emitting diode which produces output radiation of a different wavelength and of intensity representative of the intensity of the incident radiation.
