Room-temperature plasma waves resonant detection of sub-terahertz radiation by nanometer field-effect transistor

We report on room-temperature, resonant detection of 0.6THz radiation by 250nm gate length GaAs∕AlGaAs heterostructure field-effect transistor. We show that the detection is strongly increased (and becomes resonant) when the drain current increases and the transistor is driven into the current satur... View More
