The Study of Graphene Gas Sensor
Original language description
The graphene is suitable for gas sensing applications for its two dimensional character which gives the best possible ratio between sensor surface and volume. The interaction between graphene surface and gas molecules can significantly change the graphene layer transport properties. Therefore graphene can serve as a sensitive layer in a gas sensor. This work is concentrated on the analysis of the conductivity of graphene layer exposed to different gases (NH3, CO2 etc.). Together with the electrical measurement on the interdigital graphene sensor a simulation based on quantum atomistic approach has been performed. We used ATK toolkit by Quantuwise based on density functional theory (DFT) models. The exchange-correlation potential is approximated withinthe generalized gradient approximation (GGA). The transport properties of the electrode-device-electrode geometry were calculated by means of non-equilibrium Green?s function formalism as implemented in ATK. Experimental conductivity chan
