中文摘要：

一个超导体单身者光子察觉者为红外线的光子察觉用电子横梁平版印刷术(EBL ) 和蚀刻的反应离子(RIE ) 基于 NbN nanowire 被制作。当在 4.2 K 在它的批评电流下面偏导很好时， NbN nanowire 对事件光子很敏感。有 1550 nm 的波长的典型电信光子被这个察觉者检测。数据分析显示有 200 nm NbN nanowire 的设备的重复的率可能直到 100 MHz，并且当在 0.95/ c 。

英文摘要：

A superconductor single photon detector based on NbN nanowire was fabricated using electron beam lithography （EBL） and reactive ion etching （RIE） for infrared photon detection. When biased well below its critical current at 4.2 K, NbN nanowire is very sensitive to the incident photons. Typical telecommunication photons with a wavelength of 1550 nm were detected by this detector. Data analysis indicates the repeating rate of the device with 200 nm NbN nanowire may be up to 100 MHz, and the quantum efficiency is about 0,01% when biased at 0.95/c.
