title: Graphene Nucleation Preferentially at Oxygen-Rich Cu Sites Rather Than on Pure Cu Surface.
abstract: 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.
