Graphene on nickel is a few monolayers thick, usually between 1-7 layers with an average of 4 monolayer thickness. It looks like a patchwork, whereas each “patch” has a different thickness. The graphene layers within the same patch are aligned relative to each other (there is a graphitic AB-stacking order). The size of each patch is about 3-10 microns.
