Light emission from higher-order correlated excitonic states has been recently reported in hBN-encapsulated monolayer WSe<sub>2</sub> and WS<sub>2</sub> upon optical excitation. These exciton complexes are found to be bound states of excitons residing in opposite valleys in momentum space, a promising feature that could be employed in valleytronics or other novel optoelectronic devices. However, electrically-driven light emission from such exciton species is still lacking. Here we report electro ...[more]
