Suspended Monolayer Graphene on Cavities

Suspended Monolayer Graphene on Cavities

This is a tailor made graphene product. You send your substrate to our laboratory and we then use our innovative method to transfer large area CVD graphene monolayer on top of the cavities. 


Substrate requirements

  • · Substrate size up to 1.5 cm x 1.5 cm
  • · Substrate withstand 450ºC Temperature
  • · Cavity size up to 30 μm
  • · Minimum cavity depth: 500 nm

Graphene Film

  • · Growth Method: CVD synthesis
  • · Appearance (Color): Transparent
  • · Transparency >97%
  • · Appearance (Form): Film
  • · Number of graphene layers: 1
  • · Thickness (theoretical) 0.345 nm
  • · Grain size: Up to 20 μm

Quality control

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)<1; I(D)/I(G)<0.1
  • 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.
