      Spin current depolarization under high electric fields in undoped InGaAs 

      Okamoto, N.; Kurebayashi, H.; Harii, K.; Kajiwara, Y.; Beere, H.; Farrer, I.; Trypiniotis, Theodossis; Ando, K.; Ritchie, D. A.; Barnes, C. H. W.; Saitoh, E. (2011)
      Carrier spin polarization in In0.13Ga0.87 As under high electric fields has been investigated. The spin polarization was created by optical spin orientation techniques and the inverse spin-Hall effect was employed to measure ...

      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 ...
