Abstract

Graphene's extraordinary electrical, electrochemical and structural property holds great promise for biological sensing applications. In most graphene based sensing studies, the changes in conductance are widely employed as a method for detection. Here, we propose the graphene thermoelectric property, such as the thermo power profile, can also be used for sensing purposes. We conducted a first principle study of the graphene thermoelectric sensing devices, employed the density functional theory combined with non-equilibrium green function formalism (DFT-NEGF). We found that the thermoelectric power of a graphene nano ribbon (GNR) device is significantly affected by surface attachment of molecules, which in turn can be used for single molecule sensing. Our study presents a simple thermoelectric based sensing device that may provide an alternative way of doing bio sensing.
