We offer multilayer graphene films that are about 300 monolayers (105 nm) thick on average.

These graphene films are grown on nickel foil and continuous across nickel surface steps and grain boundaries.

The graphene grown on nickel film is multilayer and is not uniform. It looks like a patchwork whereas the “patches” have different thicknesses. The graphene layers within the same patch are aligned relative to each other (there is a graphitic AB-staking order). The size of the patches is about 3-10 microns.

CVD Graphene Film on Nickel
镍基石墨烯		 4” (100mm) wafer 镍基石墨烯 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.

We offer graphene films that are predominantly single-layer graphene. These graphene films are grown on copper foil and continuous across copper surface steps and grain boundaries. Graphene is grown on both sides of the copper foil. If you require specifically graphene on one side only, please contact us directly.
Etching of the underlying copper foil allows the carbon films to be transferred to other substrates such as glass, silicon dioxide or plastic films.

To the best of our knowledge, there is no report of degradation of the CVD graphene over time when it is kept in a safe, dry place. The copper foil with single-layer graphene can exhibit some coloration due to slow oxidation of the copper foil, which does not affect the quality of the graphene film.

The graphene film is mostly monolayer and has 10%-30% bilayer islands
Single/double layer graphene is a cost-effective alternative to monolayer graphene on Cu foil.
