Monolayer Graphene on PET (4" Wafer)


Monolayer Graphene on PET (4" Wafer)

Our monolayer graphene on PET (4” wafer, fully covered) is produced by CVD and transferred to a circular substrate of PET (175 μm thickness) by a wet transfer process.

Its quality, shape, size and applications make it a benchmark product in the graphene market.

Graphene Film

  • Transparency: > 97%
  • Coverage: > 95%
  • Thickness (theoretical): 0.345 nm
  • FET Electron Mobility on Al2O3: 2000 cm2/Vs
  • Hall Electron Mobility on SiO2/Si: 4000 cm2/Vs
  • Sheet Resistance: 580±50 Ohms/sq (1cm x 1cm)
  • Grain size: Up to 10 μm

PET Substrate

  • Thickness: 175μm

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: I(G)/I(2D)<0.5; 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.
