Graphene on Your Substrate - Processed in ISO 7 Cleanroom
This is a tailor made graphene product. You send your substrate to our laboratory (including your order ID and your email address as a reference) and we then use our innovative method to transfer the graphene monolayer on top of it and send it to the address you specify. Examples of substrates we have successfully transferred graphene to: devices, solar cells, LEDs, gold, alumina, silver mirrors and sapphire.

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.
