Tamer Elkhatib, et al., "Enhanced plasma wave detection of terahertz radiation using multiple high electron-mobility transistors connected in series." IEEE transactions on microwave theory and techniques 58, (2), 2010, 331. We report on enhanced room-temperature detection of terahertz radiation by several connected field-effect transistors. For this enhanced nonresonant detection, we have designed, fabricated, and tested plasmonic structures consisting of multiple InGaAs/GaAs pseudomorphic high electron-mobility transistors connected in series. Results show a 1.63-THz response that is directly
