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…
Enhancement of valley polarization at high photoexcited densities in MoS2 monolayers
Fabian Cadiz, Stefan Gerl, Takashi Taniguchi +1
We have investigated the steady-sate valley polarization and valley coherence of encapsulated MoS2 monolayer as a function of the temperature and the power density with a continuou…
Efficient valley polarization of charged excitons and resident carriers in MoS2 monolayers by optical pumping
Sangjun Park, Steve Arscott, Takashi Taniguchi +3
We investigate with polarized microphotoluminescence the optical pumping of the valley degree of freedom in charge-tunable MoS2 monolayers encapsulated with hexagonal boron nitride…
Imaging Seebeck drift of excitons and trions in MoSe2 monolayers
Sangjun Park, Bo Han, Caroline Boule +10
Hyperspectral imaging at cryogenic temperatures is used to investigate exciton and trion propagation in MoSe monolayers encapsulated with hexagonal boron nitride (hBN). Under a…
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…
