资源简介：
The Quantum Capacitance Detector (QCD) is a high-sensitivity direct detector under development for low background applications such as far-infrared spectroscopy from a cold space telescope. The QCD has demonstrated an optically-measured noise equivalent power of 2⋅10-20 W⋅Hz-1/2 at 1.5 THz, making it among the most sensitive far-infrared (IR) detectors systems ever demonstrated, and meeting the requirements for spaceborne spectroscopy. The device is also intrinsically fast, and thus able to count individual far-IR photons. Here we report a new 2-D array yielding 291 QCDs out of 441 pixels patterned, demonstrating photon-counting in a large scale. A readout technique was developed to reveal the presence or absence of a photon within a frame by a single number, providing a way to scale up to even larger arrays while maintaining a modest data rate need.
