Graphene Nucleation Preferentially at Oxygen-Rich Cu Sites Rather Than on Pure Cu Surface

Graphene nucleation at oxygen‐rich Cu sites instead of on the commonly assumed pure Cu surface is discovered using high‐spatial‐resolution scanning Auger electron microscopy, which reveals a strong O signal existing underneath the graphene seeds, along with density functional theory calculations....
