摘要

在0.65 THz和4.2 K下，对基于超导氮化铌(NbN)热电子热辐射计(HEBs)的太赫兹(THz)直接探测器进行了热偏置、微波偏置和太赫兹偏置的研究。对电流响应度和噪声等效功率(NEP)进行了测量和比较。具有毫瓦和太赫兹偏置的探测器的电流响应率比热探测器高一个数量级。在MW偏置的情况下，通过适当选择MW频率和功率，可以得到$\ mathm {pW}/\surd\ mathm {Hz}$阶的NEP。

Terahertz (THz) Direct Detectors based on Superconducting HEBs with Thermal, Microwave and THz Biasing

Terahertz (THz) direct detectors based on superconducting niobium nitride (NbN) hot electron bolometers (HEBs) with thermal, microwave (MW) and THz biasing have been studied at 0.65 THz and 4.2 K in detail. The current responsivity and noise equivalent power (NEP) have been measured and compared respectively. The detectors with the MW and THz biasing have about one order higher current responsivity than that of the thermal one. With the MW biasing, an NEP at the order of $\mathrm{pW}/\surd\mathrm{Hz}$ is obtained by choosing the MW frequency and power appropriately.
