Abstract
An infrared detector and method of detection based on depletion of charge stored in localized states is disclosed. The detector and method involve the determination of the depletion of charge stored in localized states at low temperatures caused by electric field-assisted photoemission of charge carriers from the localized states. The depletion of stored charge is indicative of the integrated incident flux of infrared radiation. The depletion of stored charge can be sensed by quantum mechanical field ionization, field detachment or otherwise.
