The Kane model is used to calculate the cyclotron mass of an electron in an InAs quantum well. The calculations were carried out in the approximation of infinity of the depth of the quantum well, taking into account the Landau level of the second subband. A graph of the dependence of the cyclotron mass mCR on the magnetic field strength for an InAs quantum well with a width L = 20 nm is obtained. Also graph of the field dependence of the Fermi energy is presented for the temperature T = 20.5 K and concentration nS = 3.6×1011 cm−2, which correspond to the experimental conditions. It is shown that taking into account the cyclotron transition of electrons within the second subband satisfactorily describes the experimental data obtained in strong magnetic fields in the InAs/In0.81Ga0.19As/InxAl1−xAs.
