Abstract We establish a powerful poly(4-styrenesulfonate) (PSS)-treated strategy for sulfur vacancy healing in monolayer MoS 2 to precisely and steadily tune its electronic state. The self-healing mechanism, which the vacancies are healed spontaneously by adatom clusters on surface through PSS-induced hydrogenation process, is proposed demonstrated systematically. electron concentration of self-healed dramatically decreased 643 times, leading work function enhancement ∼150 meV.
