Description

Monolayer Graphene Film on Cu with PMMA Coating (12 mm Diameter) - Pack 4 units

A single-layer graphene film on a copper substrate. This product is provided with a PMMA coating on top of the Graphene in order ease the transfer process and to avoid contamination. Its a high quality product, with a great homogeneity, and it is ideal for R&D departments and universities.

Graphene Film

• Growth method: CVD synthesis
• Appearance (color): Transparent
• Transparency: > 97%
• Appearance (form): Film
• Coverage: > 98%
• Number of graphene layers: 1
• Thickness (theoretical): 0.345 nm
• FET Electron Mobility on Al2O3: 2000 cm2/Vs
• Hall Electron Mobility on SiO2/Si: 4000 cm2/V
• Sheet Resistance on SiO2/Si: 450 +/- 40 Ohms/sq (1cm x1cm)
• Grain size: Up to 20 um

Substrate Cu Foil

• Thickness: 18 um
• 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

PMMA Coating

• Spin coated for high homogeneity
• Molecular weight: 495k
• Thickness: <100 nm
• PMMA model: 495K, A2

Applications

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