Spin accumulation in the extrinsic spin hall effect

The drift-diffusion formalism for spin-polarized carrier transport in semiconductors is generalized to include spin-orbit coupling. The theory is applied to treat the extrinsic spin Hall effect using

Semiclassical spin transport in spin-orbit-coupled bands.

A semiclassical theory of spin transport that is valid for spin-orbit coupled bands is developed, and an expression for the intrinsic spin-Hall conductivity of a hole-doped semiconductor agrees with the Kubo formula prediction for the same quantity.

The spin Hall effect in the presence of spin diffusion from a semiclassical Boltzmann equation is derived, and the magnitude of the spin Hall voltage due to the spin accumulation is found to be much larger than that of magnetic multilayers.

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.

Consistency in formulation of spin current and torque associated with a variance of angular momentum.

Based on the Noether's theorem, the spin-dependent formulation of the conservation laws is developed systematically and rigorously and the dependencies of the torque on the polarization and the force on the motions of spin-polarized electrons in a two-dimensional electron gas with the Rashba spin-orbit coupling are discussed.

Intrinsic spin and orbital angular momentum Hall effect.

It is shown that transport coefficients from the intrinsic origin are solely determined by local electronic structure, and thus the intrinsic spin Hall effect is not a transport phenomenon.

Spin Hall effects

In solid-state materials with strong relativistic spin-orbit coupling, charge currents generate transverse spin currents. The associated spin Hall and inverse spin Hall effects distinguish between

Intrinsic spin Hall effect in the two-dimensional hole gas.

We show that two types of spin-orbit coupling in the 2 dimensional hole gas, with and without inversion symmetry breaking, contribute to the intrinsic spin-Hall effect. Furthermore, the vertex

Generating spin currents in semiconductors with the spin Hall effect.

Using Kerr rotation microscopy to image the spin polarization, it is demonstrated that the observed spin accumulation is due to a transverse bulk electron spin current, which can drive spin polarization nearly 40 microns into a region in which there is minimal electric field.

It is shown that the electron field exerts a transverse force on an electron spin 1/2 only if the electron is moving, and this spin-dependent force can be used to understand the Zitterbewegung of the electron wave packet with spin-orbit coupling.
