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: Transparent film
Transparency: > 97%
Coverage: > 95%
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: 450Â±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

Application

Graphene research
Flexible batteries
Electronics
Aerospace industry
MEMS and NEMS
Micro actuators
Conductive coatings
