We have studied the edge spin accumulation in a high mobility two-dimensional electron gas formed in a symmetric well with two subbands. This study is strongly motivated by the recent experiment of Hernandez et al. [Phys. Rev. B {\bf 88}, 161305(R) (2013)] who demonstrated the spin accumulation near the edges of a bilayer symmetric GaAs structure in contrast to no effect in a single-layer configuration. The intrinsic mechanism of the spin-orbit interaction we consider arises from the coupling…

Effect of boundary scattering on spin-hall effect
The spin dependent reflection in quasi-two-dimensional electron gas from an impenetrable barrier in presence of Rashba and Dresselhaus spin-orbit coupling is analysed in detail. It is shown that the
Magnetoelectric torque and edge currents in spin-orbit coupled graphene nanoribbons
For graphene nanoribbons with Rashba spin-orbit coupling, the peculiar magnetic response due to the presence of a magnetization and geometric confinement are analyzed within a tight-binding model. We
Electrical control of spin relaxation anisotropy during drift transport in a two-dimensional electron gas
Spin relaxation was studied in a two-dimensional electron gas confined in a wide GaAs quantum well. Recently, the control of the spin relaxation anisotropy by diffusive motion was first shown in D.


Spin-orbit interaction in symmetric wells with two subbands.
A new intersubband-induced SO term is derived which resembles the functional form of the Rashba SO but is nonzero even in symmetric structures, which gives rise to a nonzero ballistic spin-Hall conductivity and can induce an unusual Zitterbewegung with cycloidal trajectories without magnetic fields.
Experimental observation of the spin-Hall effect in a two-dimensional spin-orbit coupled semiconductor system.
We report the experimental observation of the spin-Hall effect in a 2D hole system with spin-orbit coupling. The 2D hole layer is a part of a p-n junction light-emitting diode with a specially
Universal intrinsic spin Hall effect.
It is argued that in a high-mobility two-dimensional electron system with substantial Rashba spin-orbit coupling, a spin current that flows perpendicular to the charge current is intrinsic, and the intrinsic spin-Hall conductivity has a universal value for zero quasiparticle spectral broadening.
Spintronics: Fundamentals and applications
Spintronics, or spin electronics, involves the study of active control and manipulation of spin degrees of freedom in solid-state systems. This article reviews the current status of this subject,
Spin Hall Effect
It is proposed that when a charge current circulates in a paramagnetic metal a transverse spin imbalance will be generated, giving rise to a ``spin Hall voltage.'' Similarly, it is proposed that when
