Simulation of Energy Dependence of the Photon Absorption on the Magnetic Field in Semiconductors

The paper proposes a simple method for calculating the oscillation of joint density of states in a quantizing magnetic field with the non-quadratic dispersion law. The temperature dependence of the oscillations joint density of states in semiconductors with non-parabolic dispersion law is obtained. Moreover, the paper studies the temperature dependence of the band gap in a strong magnetic field with the non-quadratic dispersion law. The method is applied to the research of the magnetic absorption in narrow-gap semiconductors with non-parabolic dispersion law. The experimental results are interpreted with joint density of states in a strong magnetic field. Fan chart of the spectrum of magneto-absorption in narrow-gap semiconductors is constructed.
