Monolayer Graphene on Copper Foil - PMMA Coating

Monolayer Graphene on Copper Foil - PMMA Coating

from 50.00

Monolayer Graphene on Cu with PMMA Coating - Processed in Clean Room Class 1000

This product consists of single-layer graphene grown on copper foil substrate, with a PMMA Coating. 

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 passivated SiO2/Si: 6900 cm2 /Vs

  • FET Electron Mobility on SiO2/Si: 3760 cm2/Vs

  • Sheet Resistance on SiO2/Si: 450±40 Ohms/sq (1cm x1cm)

  • Grain size: Up to 20 μm

Substrate Cu Foil

  • Thickness: 18 μm

  • Roughness: around 80 nm

  • Pretreated for easier bottom layer removal: Monolayer graphene on the back side of Copper is partially removed, but not completely, so an additional treatment like RIE is needed before transfer to eliminate the bottom layer totally

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)<0.5; I(D)/I(G)<0.05

If your application requires more specific controls (AFM, SEM...) please do not hesitate to contact us.

Applications

Flexible batteries, Electronics, Aerospace industry, MEMS and NEMS, Microactuators, Conductive coatings, Research.
