Transition metal dichalcogenides possess a unique combination of properties that make them a malleable platform to study and engineer light-matter interactions. On one hand, monolayers of WS 2 naturally occur in the semiconducting 1H phase whose optical properties are dominated by excitons emerging from the band edges at the K valley. On the other hand, the 1T phase exhibits metallic properties and can be triggered by weak external stimuli. Here we use plasma irradiation to engineer a 1H/1T…
