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…
Ellipsometric study of the Electronic Structure of GaMnAs and LT-GaAs
K. S. Burch, J. Stephens, R. K. Kawakami +2
We have measured the optical constants of GaMnAs from 0.62 eV to 6 eV, using spectroscopic ellipsometry. The second derivatives of the dielectric function are examined through a cr…
Spin accumulation in forward-biased MnAs/GaAs Schottky diodes
J. Stephens, J. Berezovsky, J. P. McGuire +3
We describe a new means for electrically creating spin polarization in semiconductors. In contrast to spin injection of electrons by tunneling through a reverse-biased Schottky bar…
