Diffusive magnetotransport in a 2D Rashba system
Abstract
We present calculations of the conductivity tensor σof a 2D-system with the Rashba spin-orbit interaction (SOI) in an orthogonal magnetic field, with allowance for electron elastic scattering by a Gaussian δ-correlated random potential in the self-consistent Born approximation. The calculations are performed proceeding from the Kubo formula using a new exact epresentation of the one-particle Green function of the 2D-system with SOI in an arbitrary magnetic field. We have obtained the analytical expressions for the density of states and σwhich have a simple interpretation in terms of the two-subband model and hold good in a wide range from the classical magnetic fields (ωcτ 1) up to the quantizing ones (ωcτ 1). The numerical analysis of the Shubnikov - de Haas oscillations of the kinetic coeffitients and of their behavior in the classical fields region is performed.
