Abstract Transition-metal dichalcogenide monolayers have naturally terminated surfaces and can exhibit a near- unity photoluminescence quantum yield in the presence of suitable defect passivation. To date, steady-state monolayer light emitting devices suffer from Schottky contacts or require complex heterostructures. We demonstrate a transient-mode electroluminescent device based on transition-metal dichalcogenide monolayers (MoS2, WS2, MoSe2 and WSe2) to overcome these problems. Electroluminescence from this dopant-free two-terminal device is obtained by applying an AC voltage between the gate and the semiconductor. Notably, the electroluminescence intensity is weakly dependent on the Schottky barrier height or polarity of the contact. We fabricate a monolayer seven-segment display and achieve the first transparent and bright millimeter-scale light emitting monolayer semiconductor device.
