| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We report on design fabrication and characterization of ultrahigh sensitive terahertz detectors based on asymmetric double-grating-gate InAlAs/InGaAs/InP high electron mobility transistors. We show that an excellent coupling efficiency and nonlinear rectification response to the terahertz radiation provided by the inter-digited metal gates combined with plasmon cavities obtained by asymmetrically positioning the gate fingers in the dual-gated structure allows the achievement of a record sensitivity of 2.2 kV/W and noise equivalent power of 15 pW/Hz0.5 at 1 THz. We also demonstrate strong improvement on responsivity to 5.8 kV/W even at 1.5 THz when a dc drain-source bias is applied. | |
