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…
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…
L-valley Electron Spin Dynamics in GaAs
T. Zhang, P. Barate, C. T. Nguyen +6
Optical orientation experiments have been performed in GaAs epilayers with photoexcitation energies in the 3 eV region yielding the photogeneration of spin-polarized electrons in t…
Two kinds of spin precession modes in diluted magnetic semiconductors
M. Vladimirova, S. Cronenberger, P. Barate +3
Time-resolved Kerr rotation experiments show that two kinds of spin modes exist in diluted magnetic semiconductors: (i) coupled electron-magnetic ion spin excitations and (ii) exci…
