论文摘要

我们基于钨硅（WSI）开发了超导纳米线单光子探测器（SNSPDS），这些硅剂（WSI）显示出饱和的内部检测效率，直至10 um的波长。这些探测器有望在需要超高增益稳定性，低黑暗计数和高效率（例如化学感应，激光底，暗物质，暗物质搜索和系外行星光谱）等高效率的中红外应用中应用。

We developed superconducting nanowire single-photon detectors (SNSPDs) based on tungsten silicide (WSi) that show saturated internal detection efficiency up to a wavelength of 10 um. These detectors are promising for applications in the mid-infrared requiring ultra-high gain stability, low dark counts, and high efficiency such as chemical sensing, LIDAR, dark matter searches and exoplanet spectroscopy.
