The cyclotron-resonance spectra of hot holes in germanium have been measured at the wavelength Л = 1.65 mm in a constant electric field Е1НЦ [001]. These are the first reported measurements of this type. The results reveal an overpopulation, effects of a nonparabolic light-hole dispersion law, a cutoff of the light-hole cyclotron resonance at Ε > 500 V/cm, and the appearance of even harmonics of the heavy-hole cyclotron frequency.
