摘要

在单光子探测器热电多层传感器的设计中，我们研究了传统超导体Pb、Mo和Nb作为吸收体和散热器的特性。六硼化镧铈热电层位于吸收体和散热器之间，这三层位于介电衬底上。本文给出了工作温度在0.5 ~ 4.2 K范围内的不同几何形状传感器的热传播过程的计算机模拟结果。测定了传感器不同区域温度、信号功率、等效噪声功率和吸收能量分别为0.8、1.65和3.1 eV的单光子时的信噪比（SNR）随时间的变化规律。所得结果表明，采用Nb超导体的传感器设计可以保证在较宽的电磁波谱范围内以高效率登记吸收的单光子。

Thermoelectric Sensor of a Single-Photon Detector

We investigated the characteristics of a thermoelectric multilayer sensor of a single-photon detector in the design of which conventional superconductors Pb, Mo, and Nb are used as an absorber and a heat sink. A thermoelectric layer of lanthanum-cerium hexaboride is located between the absorber and the heat sink, and these three layers are located on a dielectric substrate. The results of computer simulation of the heat propagation process in sensors of various geometries with an operating temperature varying from 0.5 to 4.2 K are presented. The temporal dependences of the temperature in different areas of the sensor, the power of the signal arising on it, the equivalent noise power and the signal-to-noise ratio (SNR) during the absorption of single photons with an energy of 0.8, 1.65, and 3.1 eV are determined. The obtained results allow us to state that the proposed design of the sensor with a Nb superconductor can ensure the registration of absorbed single photons with a high efficiency in a wide range of the electromagnetic spectrum.
