Non-linear diffusion of negatively charged excitons in WSe2 monolayer
D. Beret, L. Ren, C. Robert +10
We investigate the diffusion process of negatively charged excitons (trions) in WSe2 transition metal dichalcogenide monolayer. We measure time-resolved photoluminescence spatial p…

Exciton spectroscopy and diffusion in MoSe2-WSe2 lateral heterostructures encapsulated in hexagonal boron nitride
Dorian Beret, Ioannis Paradisanos, Ziyang Gan +17
Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures with potential applications in optoelectronics. Critical for carrier…

Valley polarization fluctuations, bistability, and switching in two-dimensional semiconductors
M. A. Semina, M. M. Glazov, C. Robert +3
We study theoretically nonlinear valley polarization dynamics of excitons in atom-thin semiconductors. The presence of significant polarization slows down valley relaxation due to…
