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…
Enhancement of Spin Coherence using Q-factor Engineering in Semiconductor Microdisk Lasers
S. Ghosh, W. H. Wang, F. M. Mendoza +5
Semiconductor microcavities offer unique means of controlling light-matter interactions, which have led to the development of a wide range of applications in optical communications…
Fabrication and Characterization of Modulation-Doped ZnSe/(Zn,Cd)Se (110) Quantum Wells: A New System for Spin Coherence Studies
K. C. Ku, S. H. Chun. W. H. Wang, W. Fadgen +4
We describe the growth of modulation-doped ZnSe/(Zn,Cd)Se quantum wells on (110) GaAs substrates. Unlike the well-known protocol for the epitaxy of ZnSe-based quantum structures on…
Magnetoresistance Anomalies in (Ga,Mn)As Epilayers with Perpendicular Magnetic Anisotropy
G. Xiang, A. W. Holleitner, B. L. Sheu +5
We report the observation of anomalies in the longitudinal magnetoresistance of tensile-strained (Ga,Mn)As epilayers with perpendicular magnetic anisotropy. Magnetoresistance measu…
Structural, electrical, and magneto-optical characterization of paramagnetic GaMnAs quantum wells
M. Poggio, R. C. Myers, N. P. Stern +2
Growth of GaMnAs by molecular beam epitaxy is typically performed at low substrate temperatures (250C) and high As overpressures leading to the incorporation of excess As and Mn in…
Room temperature spin coherence in ZnO
S. Ghosh, V. Sih, W. H. Lau +5
Time-resolved optical techniques are used to explore electron spin dynamics in bulk and epilayer samples of n-type ZnO as a function of temperature and magnetic field. The bulk sam…
