Spin–orbit interaction and weak localization in heterostructures

Abstract

Theory of weak localization in two-dimensional high-mobility semiconductor systems is developed with allowance for the spin-orbit interaction. The obtained expressions for anomalous magnetoresistance are valid in the whole range of classically weak magnetic fields and for arbitrary strengths of bulk and structural inversion asymmetry contributions to the spin splitting. The theory serves for both diffusive and ballistic regimes of electron propagation taking into account coherent backscattering and nonbackscattering processes. The transition between weak localization and antilocalization regimes is analyzed. The manifestation of the mutual compensation of Rashba and Dresselhaus spin splittings in magnetoresistance is discussed. Perfect description of experimental data on anomalous magnetoresistance in high-mobility heterostructures is demonstrated. The in-plane magnetic field dependence of the conductivity caused by an interplay of the spin-orbit splittings and Zeeman effect is described theoretically.

Rashba and Dresselhaus Couplings in Halide Perovskites: Accomplishments and Opportunities for Spintronics and Spin–Orbitronics

“…This strategy has been used with success on various heterostructures. [95][96][97][98] Its applicability to HOP will rely probably on the the growth of clean single crystal samples with well-defined facets, as well as a better understanding of the surface defects and reconstructions.…”

“…The latter are suppressed by the precession of spins due to spin-orbit coupling leading to a weak antilocalization and a positive magnetoresistance. 95 By varying the value of the magnetic field and the gate voltage, it is then possible to determine the strength of Rashba and Dresselhaus effects. This strategy has been used with success on various heterostructures.…”

Nondiffusion theory of weak localization magnetoresistance in graphene

“…This theory may also be considered as a limit case of strong spin-orbit interaction (of Rashba or Dresselhaus type) in two-dimensional electron systems, 15 when linear in k terms in Hamiltonian dominate. The goal of this work is the theoretical study of the weak localization in graphene in the full range of classically weak magnetic fields.…”

Spin and transport effects in quantum microcavities with polarization splitting

“…10 and references therein. It was demonstrated recently that the presence of longitudinaltransverse splitting strongly affects the weak localization of exciton polaritons: the coherent backscattering can be reduced in the presence of the polariton spin splitting [11].…”
