The orientation of gas molecules and adsorption sites play an important role on charge transfer between the graphene surface and the molecules. The charge transfer mechanism is discussed in the light of molecular orbital theory. We have used three gas molecules-CO2, NH3 and NO as adsorbates and chose such orientation that adsorbates can act only as donor. Finally, we have made a conclusion that semiconducting A-GNR shows metallic behaviour after adsorbing optimum number of adsorbates corresponding to the area of A-GNR. Such semiconducting to metal transition can be used as sensing parameters. Published 2016-11-27T10:40:44Z 2016-11-27T10:40:44Z 2015 Conference Paper Shakil, S.
