Monolayer Graphene on SiO₂/Si 300 nm

Monolayer Graphene on SiO₂/Si - Fully Covered - Processed in Clean Room Class 1000

Our monolayer graphene on SiO₂/Si (fully covered) is a bidimensional material produced by CVD and transferred to a circular substrate of SiO₂/Si (300nm) by a wet transfer process. We consider it to be a benchmark product in the graphene market - not only for its excellent quality, but also for its shape, size and number of applications.

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 Clean Room Class 1000. Each batch must pass the following tests:

  • · Raman Spectroscopy on each batch: I(G)/I(2D)<0.7; I(D)/I(G)<0.05
  • · 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.
