Mapping spin-orbit splitting in strained InGaAs epilayers
B. M. Norman, C. J. Trowbridge, J. Stephens +3
Time- and spatially-resolved Faraday rotation spectroscopy is used to measure the magnitude and direction of the momentum-dependent spin splitting in strained InGaAs epilayers. The…
Non-diffusive spin dynamics in a two-dimensional electron gas
C. P. Weber, J. Orenstein, B. Andrei Bernevig +3
We describe measurements of spin dynamics in the two-dimensional electron gas in GaAs/GaAlAs quantum wells. Optical techniques, including transient spin-grating spectroscopy, are u…
Mechanical control of spin-orbit splitting in GaAs and InGaAs epilayers
V. Sih, H. Knotz, J. Stephens +3
Time-resolved Kerr rotation spectroscopy as a function of pump-probe distance, voltage and magnetic field is used to measure the momentum-dependent spin splitting energies in GaAs…
Impurity Band Conduction in a High Temperature Ferromagnetic Semiconductor
K. S. Burch, D. B. Shrekenhamer, E. J. Singley +7
The band structure of a prototypical dilute ferromagnetic semiconductor, GaMnAs, is studied across the phase diagram via optical spectroscopy. We prove that the Fermi…
Observation of spin Coulomb drag in a two-dimensional electron gas
C. P. Weber, N. Gedik, J. E. Moore +3
An electron propagating through a solid carries spin angular momentum in addition to its mass and charge. Of late there has been considerable interest in developing electronic devi…
Spatial Imaging and Mechanical Control of Spin Coherence in Strained GaAs Epilayers
H. Knotz, A. W. Holleitner, J. Stephens +2
The effect of uniaxial tensile strain on spin coherence in n-type GaAs epilayers is probed using time-resolved Kerr rotation, photoluminescence, and optically-detected nuclear magn…
