Abstract
Effect of photon drag of electrons in a semiconductor quantum wire with hydrogen-like impurity centers and Kane dispersion law
Incoming article date: 07.10.2021The article discusses the effect of photon drag (EPI) of electrons in a semiconductor quantum wire (QW) with hydrogen-like impurity centers and Kane's dispersion law, located in a longitudinal magnetic field. An analytical expression for the drag current density is obtained in the effective mass approximation, and its spectral dependence is investigated for various values of the magnetic field B and the parameters of the QW upon scattering by a system of potentials of short-range impurities. It was assumed that the QW has the shape of a circular cylinder, on the axis of which hydrogen-like impurity centers are localized. It is shown that, in the one-band approximation, taking into account the nonparabolicity of the dispersion law leads to significant dynamics of the threshold of the spectral curve. The spectral dependence is characterized by a pronounced Zeeman effect. The possibility of using an ESP for the development of photodetectors of optical radiation with a sensitivity controlled in a magnetic field is discussed.
