with different orientations, similar to the graphene grains grown on Cu foils by LP-CVD21. Note that the size of the single-crystal grains in this graphene is at least 150 m, larger than those grown on Cu foils by AP-CVD (usually about 20 m)21,22, but little smaller than the dendritic graphene grown on Cu by LP-CVD19.
It is first important to note that the predominant hexagonal graph-ene grains grown on Pt substrates have no reflex angle at the edges and no visible lines in their planes even in high-resolution scanning
electron microscope images. Second, the size of the graphene grains is inversely proportional to the nucleation de
