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…

Electron Spin Dephasing and Optical Pumping of Nuclear Spins in GaN
G. Wang, C. R. Zhu, B. L. Liu +6
We have measured the donor-bound electron spin dynamics in cubic GaN by time-resolved Kerr rotation experiments. The ensemble electron spin dephasing time in this quantum dot like…
