Single photon emitters with polarization and orbital angular momentum locking in monolayer semiconductors

2023 · arXiv (Cornell University)

Excitons in monolayer transition metal dichalcogenide are endowed with intrinsic valley-orbit coupling between their center-of-mass motion and valley pseudospin. When trapped in a confinement potential, e.g., generated by strain field, we find that intralayer excitons …
