Observation of a topologically non-trivial surface state in half-Heusler PtLuSb (001) thin films
J. A. Logan, S. J. Patel, S. D. Harrington +6
The discovery of topological insulators (TIs), materials with bulk band gaps and protected cross-gap surface states, in compounds such as Bi2Se3 has generated much interest in iden…
Surface reconstructions and transport of epitaxial PtLuSb (001) thin films grown by MBE
S. J. Patel, J. A. Logan, S. D. Harrington +2
This work presents the surface reconstructions and transport properties of the topological insulator PtLuSb grown on Al0.1In0.9Sb/GaAs (001). Two stable surface reconstructions, (1…
Spin injection from perpendicular magnetized ferromagnetic -MnGa into (Al,Ga)As heterostructures
C. Adelmann, X. Lou, H. -S. Chiang +5
Electrical spin injection from ferromagnetic -MnGa into an (Al,Ga)As p-i-n light emitting diode (LED) is demonstrated. The -MnGa layers show strong perpendicular magnetocryst…
Electron Spin Dynamics and Hyperfine Interactions in Fe/Al_0.1Ga_0.9As/GaAs Spin Injection Heterostructures
J. Strand, X. Lou, C. Adelmann +4
We have studied hyperfine interactions between spin-polarized electrons and lattice nuclei in Al_0.1Ga_0.9As/GaAs quantum well (QW) heterostructures. The spin-polarized electrons a…
