      Electron spin filtering in ferromagnet/semiconductor heterostructures 

      Bland, J. A. C.; Steinmuller, S. J.; Hirohata, A.; Cho, W. S.; Xu, Y. B.; Guertler, C. M.; Wastlbauer, G.; Ionescu, A.; Trypiniotis, Theodossis; Holmes, S. N. (2003)
      Circularly polarized light was used to generate spin-polarized electrons at room temperature in ferromagnet (FM)/GaAs Schottky diode structures. A change in the helicity-dependent photocurrent was obtained when the ...

      Highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor structures 

      Steinmuller, S. J.; Trypiniotis, Theodossis; Hirohata, A.; Cho, W. S.; Lew, W. S.; Vaz, C. A. F.; Bland, J. A. C. (2004)
      The highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor (SC) structures was discussed. It was found that the photocurrent was dependent on the relative alignment of the light helicity ...
