Charge-sensitive Infrared Phototransisotrs: Single-photon Detctors in the Long-Wavelength Infrared
Novel ultrasensitive detectors in the wavelength range of λ = 5-50 μm have developed. The detectors are charge-sensitive infrared phototransistors (CSIPs) fabricated in GaAs/AlGaAs double quantum well structures. The devices serve as a phototransistor capable of counting single photons, while a func...
