Resonance detection of terahertz radiation by nanometer field-effect transistors GaAs/AlGaAs and transistor structure GaAs/InGaAs with large area slit grating gate has been measured. For these transistors peaks in the resonance photoresponse curve are tunable with gate voltages in accordance with the Dyakonov-Shur theory.
