      Highly efficient spin filtering of ballistic electrons 

      Steinmuller, S. J.; Trypiniotis, Theodossis; Cho, W. S.; Hirohata, A.; Lew, W. S.; Vaz, C. A. F.; Bland, J. A. C. (2004)
      Spin dependent electron transport in hybrid Au/Co/Cu/NiFe/n-GaAs spin valve Schottky barrier structures was investigated using photoexcitation at various wavelengths. For excitation with the photon energy well above the ...

      Structural, magnetic, electronic, and spin transport properties of epitaxial Fe 3Si/GaAs(001) 

      Ionescu, A.; Vaz, C. A. F.; Trypiniotis, Theodossis; Gürtler, C. M.; García-Miquel, H.; Bland, J. A. C.; Vickers, M. E.; Dalgliesh, R. M.; Langridge, S.; Bugoslavsky, Y.; Miyoshi, Y.; Cohen, L. F.; Ziebeck, K. R. A. (2005)
      We report experimental results on the structural, magnetic, electronic, and spin transport properties of a 21 nm Fe 3Si/GaAs(001) heterostructure epitaxially grown by coevaporation. High-resolution x-ray diffraction shows ...

      White light emission via cascade Förster energy transfer in (Ga, In)N quantum well/polymer blend hybrid structures 

      Itskos, Grigorios; Belton, C. R.; Heliotis, G.; Watson, I. M.; Dawson, M. D.; Murray, R.; Bradley, D. D. C. (2009)
      We have studied the room-temperature non-radiative energy transfer processes in hybrid structures composed of (Ga, In)N/GaN single quantum wells and semiconducting polymer blend films placed in nanometre-scale proximity. ...
