Novel Ultra-Sensitive Detectors in the 10–50 μm Wavelength Range

Novel Ultra-Sensitive Detectors in the 10–50 μm Wavelength Range

We have developed novel single-photon detectors in the 10–50 μm wavelength region. The detectors are charge-sensitive infrared phototransistors (CSIPs) fabricated in GaAs/AlGaAs double quantum well (QW) structures, in which a photo-generated hole (+e) in the floating gate (upper QW) modulates the co...
