Graphene is a material suitable for electronic applications including sensors and biosensors operating in atmospheric conditions and at varying relative humidities. This work concerns the charge diffusion in Hall bar shaped graphene based field effect transistor that is simultaneously investigated by Kelvin probe force microscopy and macroscopic transport measurement. Furthemore it studies the possibilities of graphene Hall bar modification by local anodic oxidation, local cathodic hydrogenation and mechanical lithography. |
