Luminescence imaging of photoelectron spin precession during drift in p-type GaAs
V. Notot, D. Paget, A. C. H. Rowe +3
Using a microfabricated, p-type GaAs Hall bar, is it shown that the combined application of co-planar electric and magnetic fields enables the observation at 50 K of spatial oscill…
Ambipolar spin-spin coupling in p-GaAs
F. Cadiz, D. Paget, A. C. H. Rowe +1
A novel spin-spin coupling mechanism that occurs during the transport of spin-polarized minority electrons in semiconductors is described. Unlike the Coulomb spin drag, this coupli…
Spin dependent photoelectron tunnelling from GaAs into magnetic Cobalt
D. Vu, H. F. Jurca, F. Maroun +6
The spin dependence of the photoelectron tunnel current from free standing GaAs films into out-of- plane magnetized Cobalt films is demonstrated. The measured spin asymmetry (A) re…
Imaging charge and spin diffusion of minority carriers in GaAs
I. Favorskiy, D. Vu, E. Peytavit +3
Room temperature electronic diffusion is studied in 3 mum thick epitaxial p+ GaAs lift-off films using a novel circularly polarized photoluminescence microscope. The method is equi…
