Abstract:
Embodiments of the invention are directed to IR photodctectors with gain resulting from the positioning of a charge multiplication layer (CML) between the cathode and the IR sensitizing layer of the photodetector, where accumulating charge at the CML reduces the energy difference between the cathode and the CML to promote injection of electrons that result in gain for an electron only device. Other embodiments of the invention are directed to inclusion of the IR photodctectors with gain into an IR-to-visible up-conversion device that can be used in night vision and other applications.
