Abstract
Graphene is a two-dimensional monolayer comprised of carbon atoms. By its unique intrinsic properties, graphene has many advantages for gas sensing. In this paper, we find results of the gas sensing performance using uniform single crystal structure graphene by mechanical exfoliation method measured under room temperature, atmospheric pressure. Also, we discuss the effects of various thermal treatments on the graphene at atmospheric pressure. The sensitivity increases and recovery time decreases as measurement temperature increases.
