  Annotation. The development of technology for the growth of semiconductor nanostructures
  has led to the creation of highly efficient electronic and optoelectronic devices. It became possible
  to design multilayer structures with the necessary profile of localization, distribution of charge
  carriers and electronic spectrum. This progress would not have been possible without the
  development of methods for calculating the band structure and intensive experimental studies of
  the electrical, magnetic, and optical properties of single-crystal semiconductors. In this article,
  oscillations of interband magneto-optical absorption in semiconductors with the Kane dispersion
  law are considered. The change in the oscillations of the combined density of states with respect to
  the photon energy is compared for different Landau levels in parabolic and non-parabolic bands.
  Keywords: semiconductor, electron gas, oscillation, microwave, Landau levels, electric field,
  mathematical model, Shubnikov-de Haas oscillations.
  The combined density of states (CDS) play an important role in the interband magnetooptical
  effect [1-2]. In many cases, the matrix element changes little within the Brillouin zone. Therefore,
  the structure of the spectrum is predominantly determined by the CDS in semiconductors.
  If the initial and final states have symmetrical band spectra, then using the series expansion
  in terms of

  functions, one can find the combined density of states at any final
  temperature:

  is the combined density of states in a quantizing magnetic field at absolute zero
  temperature. This expression at T
  0 turns into (2). In this case, the Landau levels appear sharply.
