Abstract

Mono layer graphene (MLG) as a new kind of advanced material is in our focus. MLG indicates a two-dimensional structure with quantum confinement effect in its thickness. The MLG based nanomaterial has remarkable potential on electrochemical catalysis and bio-sensing applications. Recently inter sheet sensing systems for graphene sensor have been reported which will be used in our model as well. We provide a new idea of electrochemical sensors based on the graphene application. In this paper carrier the concentration on the sensor as a function of gas concentration is reported. A field effect transistor (FET) base structure as a modeling platform is proposed. Gate voltage representing the gas concentration on the sensor, or in other words the gate voltage as a function of gas concentration can be employed. Finally the proposed model is used in simulation studies and evaluated by experimental result.
