Abstract

Of the gases frequently used during graphene chemical vapor deposition (CVD),argon plays no direct chemical role and therefore may be suitable for substitutionwith the cheaper alternative of nitrogen. The impact of using nitrogen as a carriergas in methane-based hot-wall graphene CVD is investigated using Ramanspectroscopy, X-ray photoelectron spectroscopy, and time-of-flight secondary ionmass spectroscopy. No increase in the nitrogen signal is observed within gra-phene grown within a nitrogen atmosphere within the detection limits of thespectroscopic techniques used.
