      Electric control of the spin Hall effect by intervalley transitions 

      Okamoto, N.; Kurebayashi, H.; Trypiniotis, Theodossis; Farrer, I.; Ritchie, D. A.; Saitoh, E.; Sinova, J.; Mašek, J.; Jungwirth, T.; Barnes, C. H. W. (2014)
      Controlling spin-related material properties by electronic means is a key step towards future spintronic technologies. The spin Hall effect (SHE) has become increasingly important for generating, detecting and using spin ...

      Electrical determination of the spin relaxation time of photoexcited electrons in GaAs 

      Kurebayashi, H.; Trypiniotis, Theodossis; Lee, K.; Easton, S.; Ionescu, A.; Farrer, I.; Ritchie, D. A.; Bland, J. A. C.; Barnes, C. H. W. (2010)
      Spin-dependent transport for photoexcited electrons in an epitaxial Fe/GaAs interface was characterized from 5 to 300 K. The presence of spin-dependent transport was confirmed at all the measured temperatures and the spin ...

      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 ...
