Anomalous ambipolar transport in depleted GaAs nanowires
H. Hijazi, D. Paget, A C. H. Rowe +7
We have used a polarized microluminescence technique to investigate photocarrier charge and spin transport in n-type depleted GaAs nanowires ( cm doping le…
Spin/Valley pumping of resident electrons in WSe2 and WS2 monolayers
Cedric Robert, Sangjun Park, Fabian Cadiz +14
Monolayers of transition metal dichalcogenides are ideal materials to control both spin and valley degrees of freedom either electrically or optically. Nevertheless, optical excita…
Charge and spin transport over record distances in GaAs metallic n-type nanowires : II nonlinear charge transport
Hadi Hijazi, Daniel Paget, Guillaume Monier +6
We have investigated the photocarrier charge transport in n-type metallic GaAs nanowires (~ 10^17 cm^-3 doping level), grown by hydride vapor phase epitaxy (HVPE) on Si(111) substr…
Charge and spin transport over record distances in GaAs metallic n-type nanowires : I photocarrier transport in a dense Fermi sea
Hadi Hijazi, Daniel Paget, Guillaume Monier +6
We have investigated charge and spin transport in n-type metallic GaAs nanowires (~ 10^17 cm^-3 doping level), grown by hydride vapor phase epitaxy (HVPE) on Si substrates. This wa…
Exciton diffusion in WSe2 monolayers embedded in a van der Waals heterostructure
F. Cadiz, C. Robert, E. Courtade +9
We have combined spatially-resolved steady-state micro-photoluminescence (PL) with time-resolved photoluminescence (TRPL) to investigate the exciton diffusion in a WSe monol…
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…
