Electrical spin injection into InGaAs/GaAs quantum wells: a comparison between MgO tunnel barriers grown by sputtering and molecular beam epitaxy methods
P. Barate, S. Liang, T. T. Zhang +16
An efficient electrical spin injection into an InGaAs/GaAs quantum well light emitting diode is demonstrated thanks to a CoFeB/MgO spin injector. The textured MgO tunnel barrier is…
Robustness of topological states to lattice instability in non-symmorphic topological insulator KHgSb
D. Chen, T. T. Zhang, C. J. Yi +8
We report a polarized Raman scattering study of non-symmorphic topological insulator KHgSb with hourglass-like electronic dispersion. Supported by theoretical calculations, we show…
Large and robust electrical spin injection into GaAs at zero magnetic field using an ultrathin CoFeB/MgO injector
S. Liang, T. T. Zhang, P. Barate +19
We demonstrate a large electrical spin injection into GaAs at zero magnetic field thanks to an ultrathin perpendicularly magnetized CoFeB contact of a few atomic planes (1.2 nm). T…
Fabrication of an InGaAs spin filter by implantation of paramagnetic centers
C. T. Nguyen, A. Balocchi, D. Lagarde +6
We report on the selective creation of spin filltering regions in non-magnetic InGaAs layers by implantation of Ga ions by Focused Ion Beam. We demonstrate by photoluminescence spe…
