Large Area Flexible Thin Layer Terahertz Detector

Due to the low photon energy in relevant frequency band, fewer materials can directly excite carriers, and an extreme lack of high-performance, large-area detectors, limit promotion, development 6G technology. In addition, flexible detectors with integration communication Internet Things technology has good prospects for application optoelectronic devices, which are also urgently needed. A thin layer terahertz detector is designed that combines advantages excellent performance detection electromagnetic waves localized surface plasmon (LSP) effect a sub-wavelength structure detector. large effective area, spiral electrode device demonstrates best at room temperature. The noise equivalent power (NEP) photoresponsivity (RV) achieved 0.4 pW Hz−1/2 154 MV W−1 0.28 THz. bending experiments show applications.
