Probing dark excitons in atomically thin semiconductors via near-field coupling to surface plasmon polaritons

Near-field coupling to surface plasmon polaritons enables the observation of spin-forbidden dark excitonic states in monolayer WSe 2 . Transition metal dichalcogenide (TMD) monolayers with a direct bandgap feature tightly bound excitons, strong spin–orbit coupling and spin–valley degrees of freedom...
