Grain boundaries as electrical conduction channels in polycrystalline monolayer WS2
We show that grain boundaries (GBs) in polycrystalline monolayer WS2 can act as conduction channels with a lower gate onset potential for field-effect transistors made parallel, compared to devices made in pristine areas and perpendicular to GBs. Localized doping at the GB causes photoluminescence q...
