Opis

Opis ogólny

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.

Zastosowanie

• Flexible batteries.
• Electronics.
• Aerospace industry.
• MEMS and NEMS.
• Micro actuators.
• Conductive coatings.
