ABSTRACT
Cyclotron resonance photoconductivity of 2D electrons in GaAs/AlGaAs heterostructure in millimeter and submillimeter wavelength range 130 - 2700 GHz in magnetic fields up to 6 T at T = 4.2 K was investigated using backward wave tube oscillators and Fourier transform spectrometer. At low frequences the cyclotron resonance is accompanied by Shubnikov-de Haas-like oscillations of the photoconductivity. At higher frequences the response (versus magnetic field) is shown to consist of few lines corresponding to even values of the filling factor around the resonant field. Quantum Hall effect device was demonstrated to be a sensitive tunable narrow band far infrared detector.
