Valley-selective chiral phonon replicas of dark excitons and trions in monolayer WSe_{2}
We observe a set of three replica luminescent peaks at ∼21.4 meV below the dark exciton, and negative and positive dark trions (or exciton polarons) in monolayer WSe_{2}. The replica redshift energy matches the energy of the zone-center E^{′′}-mode optical phonons. The phonon replicas exhibit a para...
