Uncooled IR Detector for the Ten Micron Region

Title: Uncooled IR Detector for the Ten Micron Region
Date: 1963
Abstract: The development of an uncooled infrared detector for the 8 micron to 12 micron atmospheric window is described. In contrast to all other quantum infrared detectors, the principle of operation of the proposed detector does not involve free carrier generation by the infrared radiation. Instead, the detector shall use the absorption of infrared energy by excitons to quench an exciton-induced photoconductivity. Methods and techniques to observe exciton-induced photoconductivity and quenching by infrared radiation are discussed. Some 90 crystals were examined, and while the quenching effect was never observed, 11 of these crystals appear to exhibit the required exciton processes. The experimental procedures are being modified to emphasize the observation of exciton transport and to remove some interferences that might have inhibited or masked the quenching in previous experiments.
