Direct conversion of light-polarization information into electric voltage using photoinduced inverse spin-Hall effect in Pt/GaAs hybrid structure: Spin photodetector
Ando, K.; Morikawa, M.; Trypiniotis, Theodossis; Fujikawa, Y.; Barnes, C. H. W.; Saitoh, E. (2010)The direct conversion of light-polarization information into electric voltage has been demonstrated using the photoinduced inverse spin-Hall effect in a Pt/GaAs hybrid structure. In the GaAs layer, spin-polarized carriers ...

Electrically tunable spin injector free from the impedance mismatch problem
Ando, K.; Takahashi, S.; Ieda, J.; Kurebayashi, H.; Trypiniotis, Theodossis; Barnes, C. H. W.; Maekawa, S.; Saitoh, E. (2011)Injection of spin currents into solids is crucial for exploring spin physics and spintronics. There has been significant progress in recent years in spin injection into high-resistivity materials, for example, semiconductors ...

Photoinduced inverse spin-Hall effect: Conversion of light-polarization information into electric voltage
Ando, K.; Morikawa, M.; Trypiniotis, Theodossis; Fujikawa, Y.; Barnes, C. H. W.; Saitoh, E. (2010)The photoinduced inverse spin-Hall effect was observed in a Pt/GaAs hybrid structure. In the GaAs layer, circularly polarized light generates spin-polarized carriers, inducing a pure spin current into the Pt layer through ...

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 ...
