Anisotropic spin relaxation in -GaAs from strong inhomogeneous hyperfine fields produced by the dynamical polarization of nuclei
N. J. Harmon, T. A. Peterson, C. C. Geppert +4
The hyperfine field from dynamically polarized nuclei in n-GaAs is very spatially inhomogeneous, as the nu- clear polarization process is most efficient near the randomly-distribut…
Tuning spin orbit interaction in high quality gate-defined InAs one-dimensional channels
J. Shabani, Younghyun Kim, A. P. McFadden +3
Spin-orbit coupling in solids describes an interaction between an electron's spin, an internal quantum-mechanical degree of freedom, with its linear momentum, an external property.…
Triggering and probing of phase-coherent spin packets by time-resolved spin transport across an Fe/GaAs Schottky barrier
L. R. Schreiber, C. Schwark, S. Richter +7
Time-resolved electrical spin transport is used to generate and probe spin currents in GaAs electrically. We use high bandwidth current pulses to inject phase-coherent spin packets…
Electrical Measurement of the Direct Spin Hall Effect in Fe/In_xGa_{1-x}As Heterostructures
E. S. Garlid, Q. O. Hu, M. K. Chan +2
We report on an all-electrical measurement of the spin Hall effect in epitaxial Fe/In_{x}Ga_{1-x}As heterostructures with n-type channel doping (Si) and highly doped Schottky tunne…
Hyperfine Interactions and Spin Transport in Ferromagnet-Semiconductor Heterostructures
M. K. Chan, Q. O. Hu, J. Zhang +3
Measurements and modeling of electron spin transport and dynamics are used to characterize hyperfine interactions in Fe/GaAs devices with -GaAs channels. Ga and As nuclei are po…
Electrical Detection of Spin Transport in Lateral Ferromagnet-Semiconductor Devices
X. Lou, C. Adelmann, S. A. Crooker +6
A longstanding goal of research in semiconductor spintronics is the ability to inject, modulate, and detect electron spin in a single device. A simple prototype consists of a later…
