      Analysis of the transport process providing spin injection through an Fe/AlGaAs Schottky barrier 

      Hanbicki, A. T.; Van't Erve, O. M. J.; Magno, R.; Kioseoglou, G.; Li, C. H.; Jonker, B. T.; Itskos, Grigorios; Mallory, R.; Yasar, M.; Petrou, Athos Chariton (2003)
      Electrical injection through a reverse biased Fe/AlGaAs Schottky contact was used to obtain electron-spin polarizations in a GaAs quantum well. The analysis of the transport data using the Rowell criteria shows that ...

      Electrical spin injection and band offsets in an n-type ferromagnetic semiconductor heterostructure: n-CdCr2Se4/AlGaAs/GaAs 

      Jonker, B. T.; Hanbicki, A. T.; Kioseoglou, G.; Li, C. H.; Stroud, R. M.; Sullivan, J. M.; Erwin, S. C.; Lüpke, G.; Zhao, H. B.; Ren, Y. H.; Sun, B.; Itskos, Grigorios; Mallory, R.; Yasar, M.; Petrou, Athos Chariton (Institute of Electrical and Electronics Engineers Inc., 2003)
      Electrical spin injection and band offsets in an n-type ferromagnetic semiconductor heterostructure of CdCr2Se4-AlGaAs-GaAs are studied. Epitaxially grown CdCr2Se4 films exhibit hysteresis behavior with significant remanence, ...

      A schottky tunnel barrier contact for electrical spin injection from a magnetic metal into a semiconductor 

      Hanbicki, A. T.; Stroud, R. M.; Magno, R.; Kioseoglou, G.; Li, C. H.; Jonker, B. T.; Itskos, Grigorios; Mallory, R.; Yasar, M.; Petrou, Athos Chariton (2003)
      A study was performed on a Schottky tunnel barrier contact for electrical spin injection from a magnetic metal into a semiconductor. It was reported that spin injection from a Fe Schottky contact produced a spin polarization ...
