Ambipolar carrier conduction has been observed in a metal-insulator-semiconductor field-effect transistor made using ͑BEDT-TTF͒͑TCNQ͒ crystals. The temperature dependence of the source current with the applied positive gate voltage exhibits metal-like behavior at around room temperature. The metal-like conduction transforms into thermal-activation-type behavior below 240 K. The I S -V DS curve for an applied gate voltage of 80 V exhibited a corresponding change in the curvature below 240 K.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
