Nitrogen Tracers in Graphene

A nitrogen doping agent on a layer of graphene.  

After applying trace amounts of nitrogen to a monolayer of graphene, scientists could alter the graphene’s electronic properties. Scientists hope to further develop nitrogen doping agents to create high-quality graphene films.
