Abstract
With the help of mathematical models, the temperature dependence of the density of energy states was determined in a quantizing magnetic field. The influence of the effective mass at the temperature dependence of the density of the energy states in a strong quantizing magnetic field is investigated. The dependence temperature of density of energy states graph is obtained in a strong magnetic field for InSb.

In narrow-gap semiconductors, the effective mass of electrons is small, so that the quantization condition is observed in weak magnetic fields
The distance between Landau levels was greater than the characteristic electron energy
In a strong magnetic field, the energy spectrum of free electrons and holes are undergoing serious changes, which is reflected by the density of the energy states
Summary
In narrow-gap semiconductors, the effective mass of electrons is small, so that the quantization condition is observed in weak magnetic fields. In such conditions, the distance between Landau levels was greater than the characteristic electron energy. The distance between Landau levels was greater than the characteristic electron energy In these conditions, it is possible to find the effective mass mc* = eH ωcc. If the dependence of the energy of the wave vector is not described by a quadratic form, for example, the electron in InSb energy levels of the charge carriers in the magnetic field is not at equidistants, such as the cyclotron mass, but is given by mc*.
