We have studied the adsorption of gas molecules (CO, NO, NO2, O2, N2, CO2,and NH3) on graphene nanoribbons (GNRs) using first principles methods. Theadsorption geometries, adsorption energies, charge transfer, and electronicband structures are obtained. We find that the electronic and transportproperties of the GNR with armchair-shaped edges are sensitive to theadsorption of NH3 and the system exhibits n type semiconducting behavior afterNH3 adsorption. Other gas molecules have little effect on modifying theconductance of GNRs. Quantum transport calculations further indicate that NH3molecules can be detected out of these gas molecules by GNR based sensor.
