Since graphene has high carrier mobility, graphene field-effect transistor (GFET) can track adsorption on the graphene surface with high sensitivity through changes in peak voltage values. Furthermore, ionic liquid gated GFET (ILGFET), which are complexed with ionic liquids, can be driven at low voltages and are expected to be deployed in low concentration gas sensors. In this study, we report an ILGFET that shows a response to Nitrate-nitrogen gas.
