Electron spin polarization induced by spin Hall effect in semiconductors   with a linear in the momentum spin-orbit splitting of conduction band
  It is shown that spin Hall effect creates uniform spin polarization of electrons in semiconductor with a linear in the momentum spin splitting of conduction band. In turn, the profile of the non-uniform spin polarization accumulated at the edge of the sample oscillates in space even in the absence of an external magnetic field.
