The suitability of NbRe as a promising material for the design of Superconducting Single Photon Detectors is investigated in order to lower both the minimum detectable photon energy and the recovery time of the devices. Both the low values determined for the quasiparticle relaxation time, τE, and its weak temperature dependence are desirable in the design of fast single photon detectors. Both properties can be further improved by coupling NbRe with a ferromagnetic layer, as demonstrated by estimating the characteristic relaxation rates in NbRe/CuNi bilayers.

NbRe 作为快速单光子检测的候选材料

研究了 NbRe 作为设计超导单光子探测器的有前途的材料的适用性，以降低设备的最小可探测光子能量和恢复时间。在快速单光子探测器的设计中，准粒子弛豫时间 τE 确定的低值及其弱的温度依赖性都是理想的。如通过估计 NbRe/CuNi 双层中的特征弛豫率所证明的那样，通过将 NbRe 与铁磁层耦合可以进一步改善这两种特性。
