The triatomic and tetratomic gas molecule adsorption effects on the electrical conductivity of graphene are investigated by the tight-binding model, Green's function method, and coherent potential approximation. We find that the electrical conductivity of graphene sheet is sensitive to the adsorption of these gases.

The incorporation of a variety of additional physical/passive and catalytically active/chemical filters into the measuring unit or directly into the sensor construction is one of the most effective methods for improving both sensor selectivity and sensor resistivity to poisoning. The present chapter describes the materials used for fabrication of these
