      Efficient electrical spin injection from a magnetic metal/tunnel barrier contact into a semiconductor 

      Hanbicki, A. T.; Jonker, B. T.; Itskos, Grigorios; Kioseoglou, G.; Petrou, Athos Chariton (2002)
      We report electrical spin injection from a ferromagnetic metal contact into a semiconductor light emitting diode structure with an injection efficiency of 30% which persists to room temperature. The Schottky barrier formed ...

      Spin transport in germanium at room temperature 

      Shen, C.; Trypiniotis, Theodossis; Lee, K. Y.; Holmes, S. N.; Mansell, R.; Husain, M.; Shah, V.; Li, X. V.; Kurebayashi, H.; Farrer, I.; De Groot, C. H.; Leadley, D. R.; Bell, G.; Parker, E. H. C.; Whall, T.; Ritchie, D. A.; Barnes, C. H. W. (2010)
      Spin-dependent transport is investigated in a Ni/Ge/AlGaAs junction with an electrodeposited Ni contact. Spin-polarized electrons are excited by optical spin orientation and are subsequently used to measure the spin dependent ...
