| 英文摘要 | We report the terahertz direct detection characteristics of a spiral antenna coupled NbN superconducting hot-electron bolometer (HEB) at a bath temperature of 4.2K. Thermal conductance determined from resistance transition curves with different bias currents is found to be 3 x 10(-7) W/K. The device shows a read-out circuit limited noise equivalent power (NEP) of 4.5x10(-12) W/Hz(1/2) at 4.2K with a home-made transimpedance amplifier operating at room temperature. |
