Electroluminescence from multi-particle exciton complexes in transition metal dichalcogenide semiconductors
Abstract
The emission of light from correlated excitonic complexes has been recently observed in atomically thin transition metal dichalcogenides. Here, the authors report electroluminescence generated by a pulsed gate voltage from excitons, trions, and biexcitons in monolayer WSe2 and WS2 encapsulated with hBN.
