Probing, understanding, and manipulating nontrivial excitonic transport in atomically thin transition metal dichalcogenides (TMDCs) is a long-standing challenge. Here, the authors report the observation of ultrafast spatial hole burning of excitonic emission in monolayer WS2 and reveal the underlying mechanism, showcasing the peculiar excitonic transportation in monolayer TMDCs.
