Monolayer Graphene on Quartz - Processed in ISO 7 Cleanroom
Our monolayer graphene on Quartz (fully covered) is produced by CVD and transferred to a circular substrate of Quartz (500 μm thickness) by a semi-dry transfer process. Its high quality and wide range of applications make it a benchmark product in the graphene market.

All our samples are subjected to a rigorous QC in order to ensure a high quality and reproducibility of the graphene. All our CVD materials are processed in Clean Room Class 1000. Each batch must pass the following tests:
- · Raman Spectroscopy on each batch: I(G)/I(2D)<1; I(D)/I(G)<0.1 on 90nm SiO2/Si substrate.
- · Optical Microscopy inspection of each individual sample to ensure good transfer quality and purity
If your application requires more specific controls (AFM, SEM...) please do not hesitate to contact us.
