Numerical study of spin Hall transport in a two-dimensional hole-gas system
We present a numerical study of the spin Hall effect in a two-dimensional hole gas system in the presence of disorder. We find that the spin Hall conductance SHC , extrapolated to the thermodynamic limit, remains finite in a wide range of disorder strengths for a closed system on torus. But there is no intrinsic spin Hall accumulation as induced by an external electric field once the disorder i...
متن کاملSpin-Hall conductivity in a two-dimensional Rashba electron gas
Spin-Hall conductivity and Pauli susceptibility of 2D electron gas with Rashba spin-orbital interaction is studied theoretically in the semiclassical limit kFl 1. Static spin-Hall conductivity is shown to be zero for any nonvanishing disorder strength in the general case of the momentum-dependent Rashba velocity p and nonparabolic spectrum p . This result is derived both by an explicit diagramm...
متن کاملSpin transition of a two-dimensional hole system in the fractional quantum Hall effect
The effect of the complex valence-band Landau-level ~LL! structure on the fractional quantum Hall ~FQH! effect of a two-dimensional hole system has been studied in a modulation-doped quantum well ~QW! with front and back gates. Owing to the spin-orbit interaction and the band mixing in the valence band, changing the potential asymmetry of the QW with the front and back gates allows us to vary t...
متن کاملPlasmons in spin-orbit coupled two-dimensional hole gas systems
We study the dynamical dielectric function of a two-dimensional hole gas, exemplified on [001] GaAs and InAs quantum wells, within the Luttinger model extended to the two lowest subbands including bulk and structure inversion asymmetric terms. The plasmon dispersion shows a pronounced anisotropy for GaAsand InAs-based systems. In GaAs this leads to a suppression of plasmons due to Landau dampin...
متن کاملBallistic spin transport in a two-dimensional electron gas
We explore electrically injected, spin-polarized transport in a ballistic two-dimensional electron gas. We augment the Büttiker-Landauer picture with a simple, but realistic model for spin-selective contacts to describe multimode reservoir-to-reservoir transport of ballistic spin-1/2 particles. Clear and unambiguous signatures of spin transport are established in this regime, for the simplest m...
