Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides

Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides

The nature of defects in transition metal dichalcogenide semiconductors is still under debate. Here, the authors determine the atomic structure and electronic properties of chalcogen-site point defects common to monolayer MoSe2 and WS2, and find that these are substitutional defects, where a chalcog...
