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 filmGrowth method: CVD synthesisAppearance: Transparent filmTransparency: > 97%Coverage: > 95%Number of graphene layers: 1Thickness (theoretical): 0.345 nmFET Electron Mobility on Al2O3: 2000 cm2/VsFET Electron Mobility on SiO2/Si: 4000 cm2/VsSheet Resistance on SiO2/Si: 450±40 Ω/sq (1cm x1cm)Grain size: Up to 10 μmSubstrate Cu FoilThickness: 18 μmPre-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 CoatingSpin coated for high homogeneityMolecular weight: 495kThickness: <100 nmPMMA model: 495K, A2Graphene researchFlexible batteriesElectronicsAerospace industryMEMS and NEMSMicro actuatorsConductive coatings
