NOVELTY - The graphene electronic device comprises a substrate (110) configured to act as a gate electrode, a layer of gate oxide (112) disposed on the substrate, a layer of hydrophobic polymer such as hexamethyldisilazane disposed on the gate oxide of the substrate, a graphene channel layer (130) disposed on the hydrophobic polymer, a source electrode (142) placed on one end of the graphene channel layer, a drain electrode placed on another end of the graphene channel layer, and a passivation layer covering the graphene channel layer exposed by the source electrode and the drain electrode. USE - Used as a graphene electronic device such as a top/bottom gate-type transistor, FET and radio frequency transistor. ADVANTAGE - The graphene electronic device exhibits improved electrical characteristics, high resistance, increased carrier mobility and capacitance and reduced impurity, and is easy to operate at room temperature. DETAILED DESCRIPTION - The graphene electronic device comprises a substrate (110) configured to act as a gate electrode, a layer of gate oxide (112) disposed on the substrate, a layer of hydrophobic polymer such as hexamethyldisilazane disposed on the gate oxide of the substrate, a graphene channel layer (130) disposed on the hydrophobic polymer, a source electrode (142) placed on one end of the graphene channel layer, a drain electrode placed on another end of the graphene channel layer, and a passivation layer covering the graphene channel layer exposed by the source electrode and the drain electrode. The hydrophobic polymer has a thickness of 10-100 nm. The passivation layer has a thickness of 5-30 nm. The graphene channel layer comprises one of a mono-layer and/or a bi-layer graphene, and is disposed on the hydrophobic polymer. The gate oxide covers the graphene channel layer exposed by the source electrode and the drain electrode. An INDEPENDENT CLAIM is included for a method of fabricating a graphene electronic device.
