In article number 1800342 , Sang‐Woo Kim and co‐workers report a large‐scale MoS 2 ‐nanosheet‐based high‐performance piezoelectric nanogenerator via passivation of sulfur vacancies causing a screening effect of piezoelectric polarization charges. The sulfur‐treatment process fills the sulfur vacancies with sulfur atoms, and the sulfur‐treated MoS 2 shows dramatic enhancement of piezoelectric properties compared to pristine MoS 2 .
