Cyclotron-phonon resonance with phonon absorption in n-InSb
Leshko O. M. , Sheregii E. M.
Peaks have been discovered in the magnetic-field dependence of the photoconductivity of я-InSb in fields up to 400 kOe at T> 80 K. The positions of these peaks along the field scale and their temperature dependence provide evidence that this is the first observation of a cyclotron-phonon resonance involving an absorption of phonons.
