Abstract

In this work, the influence of two-dimensional state density on oscillations of transverse electrical conductivity in heterostructures with rectangular quantum wells is investigated. A new analytical expression is derived for calculating the temperature dependence of the transverse electrical conductivity oscillation and the magnetoresistance of a quantum well. For the first time, a mechanism is developed for oscillating the transverse electrical conductivity and magnetoresistance of a quantum well from the first-order derivative of the magnetic field (differential) \(\frac{{\partial \left( {\rho_{ \bot }^{2d} (E,B,T,d)} \right)}}{\partial B}\) at low temperatures and weak magnetic fields. The oscillations of electrical conductivity and magnetoresistance of a narrow-band quantum well with a non-parabolic dispersion law are investigated. The proposed theory investigates the results of experiments of a narrow-band quantum well (InxGa1−xSb). The experiment shows that the oscillations of the transverse magnetoresistance of the InxGa1−xSb quantum filament, measured at a temperature of 2 K, transform into a continuous energy spectrum due to thermal washing under the influence of the temperature growth dynamics.
