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…

Magnetic imaging with spin defects in hexagonal boron nitride
P. Kumar, F. Fabre, A. Durand +13
Optically-active spin defects hosted in hexagonal boron nitride (hBN) are promising candidates for the development of a two-dimensional (2D) quantum sensing unit. Here, we demonstr…

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…
