In the far-infrared (THz) field, single-walled carbon nanotubes (SWCNTs) are promising candidates for room-temperature and self-powered thermal detectors due to their low specific heat capacity, high stability, relatively large Seebeck coefficients, and the ability to be doped diversely. Especially when the nanotubes are aligned, the photoresponse becomes polarization-sensitive. In this work, we integrated a bowtie antenna stereostructure with a horizontally aligned SWCNTs film to generate new resonance modes and gain mechanisms to improve the polarization extinction ratio (PER) and the response of carbon nanotube far-infrared detectors. While the antenna size changes, we can get PERs higher than 6481 from 0.5THZ to 1.5 THz.
