title = "Ammonia sensing properties of centimeter scaled CVD graphene in ambient condition",
abstract = "The present work reports ammonia (NH 3) gas sensing properties of Graphene film synthesized by chemical vapor deposition (CVD) in ambient condition. Graphene with a large area as centimeter scale was synthesized on Cu foils by chemical vapor deposition under ambient pressure and has transferred onto Si/SiO 2 wafer. By fabricating ohmic contact to both side of graphene layer, we measured DC resistance changes with respect to NH 3 gas flow. The gas molecules are absorbed on graphene by chemisorption and causes resistance change of graphene which is increasing by electron injection from ammonia molecules. The sensing characteristics of graphene has been examined by changing the inlet gas flow and the sensor shows better performance with large flow, such as fast response time and high sensitivity.",
