Enhancing Photoluminescence and Mobilities in WS₂ Monolayers with Oleic Acid Ligands

Abstract

monolayers in a manner akin to the passivation of colloidal quantum dots with OA ligands. Our results open up a new pathway to passivate and tune defects in monolayer TMDs using simple "wet" chemistry techniques, allowing for trap-free electronic properties and bright neutral exciton and trion emission.
