| We report on terahertz radiation detection with InGaAs/InAlAs Field EffectTransistors in quantizing magnetic field. The photovoltaic detection signal isinvestigated at 4.2 K as a function of the gate voltage and magnetic field.Oscillations analogous to the Shubnikov-de Haas oscillations, as well as theirstrong enhancement at the cyclotron resonance, are observed. The results arequantitatively described by a recent theory, showing that the detection is dueto rectification of the terahertz radiation by plasma waves relatednonlinearities in the gated part of the channel. |
