Nanomateriali per la ricerca e per l'industria

Graphene Film

• · Growth method: CVD synthesis
• · Appearance (color): Transparent
• · Transparency: > 97%
• · Coverage: > 95%
• · Number of graphene layers: 1
• · Thickness (theoretical): 0.345 nm
• · AFM Thickness (air @RT): <1nm
• · Electron Mobility on SiO₂/Si: ≈1500 cm²/V·s
• · 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)<0.1

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