Abstract: A graphene device including separated junction contacts and a method of manufacturing the same are disclosed. The graphene device is a field effect transistor (FET) in which graphene is used as a channel. A source electrode and a drain electrode do not directly contact the graphene channel, and junction contacts formed by doping semiconductor are separately disposed between the graphene channel and the source electrode and between the graphene channel and the drain electrode. Therefore, in an off state where a voltage is not applied to a gate electrode, due to a barrier between the graphene channel and the junction contacts, carriers may not move. As a result, the graphene device may have low current in the off state.
