Single-walled carbon nanotubes (SWCNTs) enable infrared radiation detection through a combination of far-infrared plasmon resonance excitation and thermoelectric response due to subsequent heat generation accompanied by temperature rise. This pseudo-photo-thermoelectric (PTE) effect of SWCNTs realizes uncooled and broadband optical detection. In this study, we demonstrate a pseudo-PTE response exceeding mV by far-infrared and terahertz light irradiation with an infrared thermoelectric sensor based on high-purity semiconducting SWCNTs.
