Exciton dynamics in WSe2 bilayers
G. Wang, X. Marie, L. Bouet +5
We investigate exciton dynamics in 2H-WSe2 bilayers in time-resolved photoluminescence (PL) spectroscopy. Fast PL emission times are recorded for both the direct exciton with $τ_{D…
Charge tuning in [111] grown GaAs droplet quantum dots
L. Bouet, M. Vidal, T. Mano +10
We demonstrate charge tuning in strain free GaAs/AlGaAs quantum dots (QDs) grown by droplet epitaxy on a GaAs(111)A substrate. Application of a bias voltage allows the controlled c…
Non-linear Optical Spectroscopy of Excited Exciton States for Efficient Valley Coherence Generation in WSe2 Monolayers
G. Wang, X. Marie, I. Gerber +6
Monolayers (MLs) of MoS2 and WSe2 are 2D semiconductors with strong, direct optical transitions that are governed by tightly Coulomb bound eletron-hole pairs (excitons). The optoel…
Robust optical emission polarization in MoS2 monolayers through selective valley excitation
G. Sallen, L. Bouet, X. Marie +8
We report polarization resolved photoluminescence from monolayer MoS2, a two-dimensional, non-centrosymmetric crystal with direct energy gaps at two different valleys in momentum s…
