Monolayer Graphene on Quartz

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.

Quality control

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 ISO 7 Cleanroom. 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.

Applications

Solar cells, Touch-screens and displays, Photodetectors, Light harvesting devices
