Photon-induced spin transport in two-dimensional electron systems
We study spin-dependent transport in a two-dimensional electron gas subject to
 an external step-like potential V(x) and irradiated by an electromagnetic field (EF). In the absence of EF the electronic spectrum splits into spin sub-bands originating from
 the "Rashba" spin-...

| description | We study spin-dependent transport in a two-dimensional electron gas subject to
an external step-like potential V(x) and irradiated by an electromagnetic field (EF). In the absence of EF the electronic spectrum splits into spin sub-bands originating from
the "Rashba" spin-orbit coupling. We show that the resonant interaction of
propagating electrons with the component EF parallel to the barrier induces a nonequilibrium dynamic gap (2ΔR ) between the spin sub-bands. Existence of this gap
results in coherent spin-flip processes that lead to a spin-polarized current and a large
magnetoresistance, i.e. the spin valve effect. These effects may be used for controlling spin transport in semiconducting nanostructures, e.g. spin transistors, spin-blockade devices etc., by variation of the intensity S and frequency ω of the external radiation.
