General description

A single-layer graphene film on a copper substrate.
This product is provided with a PMMA coating on top of the graphene in order to ease the transfer process and to avoid contamination. It′s a high quality product with great homogeneity.

Graphene Film:
  • Growth method: CVD synthesis.
  • Appearance (color): Transparent.
  • Transparency: >97%.
  • Coverage: >98%.
  • Number of graphene layers: 1.
  • Thickness (theoretical): 0.345 nm.
  • FET electron mobility on Al2O3: 2000 cm2/Vs.
  • FET electron mobility on SiO2/Si: 4000 cm2/Vs.
  • Sheet resistance on SiO2/Si: 450±40 Ω/sq (1cm x1cm).
  • Grain size: Up to 10 μm.

Substrate Cu Foil:
  • Thickness: 18 μm.
  • Pre-treated for easier bottom layer removal. Monolayer graphene on the back side of copper is partially removed, but not completely. Therefore, an additional treatment like RIE is needed before transfer to eliminate the bottom layer totally.

PMMA Coating:
  • Spin coated for high homogeneity.
  • Molecular weight: 495k.
  • Thickness: <100 nm.
  • PMMA model: 495k, A2.
We are committed to bringing you Greener Alternative Products that adhere to one of the four categories of Greener Alternatives.
