The results account very well for experimental results including the tunneling of photoexcited electrons and suggest that the spin polarization (from −100% to 100%) is dependent on the Schottky barrier height. They also suggest that the sign of the spin polarization can be controlled with a bias voltage.}, pages = {245316--245316}, title = {Spin polarization control through resonant states in an Fe/GaAs Schottky barrier}, volume = {78}, year = {2008} }
