Abstract(in English) | We report on the design of spiral-MKIDs for THz wave real-time imaging and the fabrication and evaluation of 4K operation devices using NbN thin films. We fabricated spiral-MKIDs with different film thicknesses using deposition conditions for epitaxially grown NbN films on m-plane sapphire substrates, and experimentally clarified that the response characteristics of the electromagnetic wave and the unloaded Q values of the devices have a trade-off relationship with the NbN film thickness. In addition, the film thickness dependence of noise equivalent power (NEP) gave an optimum film thickness of 3 to 4 nm and NEP ~ 1.0×10-13 W/Hz1/2 @ 3.7 K. |
