The conductivity of electron gas quantized by electromagnetic field at photovoltaic effect

Abstract

The paper studies a 2D semiconductor consisting of heavy holes and light electrons. The basic condition is that the electrons are quantized by an electromagnetic field, and the holes are classic. It is assumed that the interaction between the components is weak or absent. The paper uses the kinetic equation for the holes that encounter with the quantizing electrons. It is found that the re-sistance and corresponding amendment to the scattering conductivity σxx do not disappear at zero temperature due to the influence of the Landau levels. This amendment arises when the Fermi level crosses the Landau level. The limits of applying the kinetic equation are found and the phenom-enon of kinetic memory is considered when the particles repeatedly return to their venues.
