Temperature dependence of graphene and N-doped graphene for gas sensor applications

© Published under licence by IOP Publishing Ltd. We report the response of graphene and N-doped graphene to ethanol vapor as gas sensors with varying the concentration of ethanol and temperature of graphene. Graphene was synthesized by chemical vapor deposition on copper foils and then was transferr...
