Abstract
We present the possibility of using magnetic field to enhance responsi vity and to tune spectral range of far-infrared InSb detector (based o n photoconductivity effect) beyond its standard range limited to about 30 cm(-1). We show that due to cyclotron resonance assisted transitio ns we can use it as a tunable detector working up to energies about 18 0 cm(-1) (22 meV). We have used such a detector as a spectrometer for measurements of the Landau emission from GaAs emitter.
