- · FET Electron Mobility on Al2O3 passivated SiO2/Si: 6900 cm2 /Vs (doi: http://dx.doi.org/10.1063/1.4972847)
- · FET Electron Mobility on SiO2/Si: 3760 cm2/Vs DOI: https://doi.org/10.1103/PhysRevLett.119.066802
- · Sheet Resistance on SiO2/Si: 450±40 Ohms/sq (1cm x1cm)
- · Grain size: Up to 20 μm
Substrate Cu Foil
- · Thickness: 18 μm
- · Roughness: around 80 nm
- · Pretreated for easier bottom layer removal: Monolayer graphene on the back side of Copper is partially removed, but not completely, so an additional treatment like RIE is needed before transfer to eliminate the bottom layer totally
All our samples are subjected to a rigorous QC in order to ensure a high quality and reproducibility of the graphene.
- · Raman Spectroscopy on each batch: I(G)/I(2D)<0.5; I(D)/I(G)<0.05
If your application requires more specific controls (AFM, SEM...) please do not hesitate to contact us.

Frequently Asked Questions
A: No. Graphene bottom layer has to be removed before transferring onto the desired substrate. Different methods can be used such as oxygen plasma, Reactive Ion Etching (RIE) or chemical reactants such as diluted HNO3.
A: We recommend to keep the samples in vacuum or inert atmosphere in order to avoid copper oxidation.
A: The main orientation is <100>.
