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 ...

Initial/final state selection of the spin polarization in electron tunneling across an epitaxial FeGaAs (001) interface
Kurebayashi, H.; Steinmuller, S. J.; Laloë, J. B.; Trypiniotis, Theodossis; Easton, S.; Ionescu, A.; Yates, J. R.; Bland, J. A. C. (2007)Spin dependent electron transport across epitaxial FeGaAs (001) interfaces has been investigated using photoexcitation techniques. Spin filtering is observed in the forward bias regime and its sign is switched by using ...

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 ...
