我们报道了用原子层沉积法制备的氮化铌超导纳米线的扩展红外单光子响应。超导纳米线单光子探测器基于4.65 nm厚的NbN，图案化为100 nm的曲折，并在2.5 K下表征。我们验证了从1310到2006 nm的单光子灵敏度，在较短的波长下具有饱和响应。
We report on the extended infrared single-photon response of niobium nitride superconducting nanowires deposited by atomic layer deposition. The superconducting nanowire single-photon detectors are based on 4.65 nm thick NbN, patterned into 100 nm meanders, and characterized at 2.5 K. We verify single-photon sensitivity from 1310 to 2006 nm with saturated response at shorter wavelengths.
