One Wafer 100mm (4 in) with CVD Graphene Film on nickel/SiO2/Si substrate

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.

Because graphene on nickel is grown in patches with different layering, the Raman signal will change dramatically depending on the spot of the film where it is taken. If nickel is used as a catalyst, it is not possible to create a graphene sheet with a precise and uniform layering.
