Ultrafast mapping of optical polarization states onto spin coherence of localized electrons in a semiconductor
S. Z. Denega, M. Sladkov, D. Reuter +3
We experimentally demonstrate an ultrafast method for preparing spin states of donor-bound electrons in GaAs with single laser pulses. Each polarization state of a preparation puls…
Optical probing of spin dynamics of two-dimensional and bulk electrons in a GaAs/AlGaAs heterojunction system
P. J. Rizo, A. Pugzlys, A. Slachter +5
We present time-resolved Kerr rotation measurements of electron spin dynamics in a GaAs/AlGaAs heterojunction system that contains a high-mobility two-dimensional electron gas (2DE…
Suppressed spin dephasing for 2D and bulk electrons in GaAs wires due to engineered cancellation of spin-orbit interaction terms
S. Z. Denega, T. Last, J. Liu +7
We report a study of suppressed spin dephasing for quasi-one-dimensional electron ensembles in wires etched into a GaAs/AlGaAs heterojunction system. Time-resolved Kerr-rotation me…
Spin-dephasing anisotropy for electrons in a diffusive quasi-1D GaAs wire
J. Liu, T. Last, E. J. Koop +3
We present a numerical study of dephasing of electron spin ensembles in a diffusive quasi-one-dimensional GaAs wire due to the D'yakonov-Perel' spin-dephasing mechanism. For widths…
