Phys. Rev. B 75, 155323 (2007) [6 pages]Anisotropic current-induced spin accumulation in the two-dimensional electron gas with spin-orbit couplingReceived 19 January 2007; published 17 April 2007 We investigate the magnetoelectric (or inverse spin-galvanic) effect in the two-dimensional electron gases with both Rashba and Dresselhaus spin-orbit couplings using an exact solution of the Boltzmann equation for electron spin and momentum. The spin response to an in-plane electric field turns out to be highly anisotropic, while the usual charge conductivity remains isotropic, contrary to earlier statements. © 2007 The American Physical Society URL:
