      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 ...

      Numerical calculation model for spin-dependent transport of photoexcited electrons across Fe/GaAs(0 0 1) interfaces 

      Kurebayashi, H.; Trypiniotis, Theodossis; Lee, K.; Moutafis, C.; Easton, S.; Ionescu, A.; Bland, J. A. C.; Barnes, C. H. W. (2010)
      abs Spin-dependent transport of photogenerated electrons across Fe/GaAs(0 0 1) interfaces is calculated using a one-dimensional electron transport model. Creation of spin-polarized electrons by photoexcitation in this model ...

      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 ...
