Abstract: Establishing the features of interfacial effects on the electrical conductivity of graphene is crucial for successful design of novel graphene-based electronic devices, including chemical sensors and biosensors. We study electrical properties of monolayer graphene, prepared by thermal decomposition of silicon carbide in argon, in the field-effect transistor and the four-probe geometries. Alterations in the electrical properties of graphene in response to placing a quantity of water on its surface followed by removal of the water are investigated. In these geometries, the field effect is shown to play a key role in the way the electrical properties of graphene are affected by the formation of the graphene–water interface.
