Description Monolayer Graphene Film PET-4 Our monolayer graphene film PET-4″ wafer (fully covered) is grown on a 50 micron-thick copper foil that is coated with single atomic layer of graphene which is deposited via chemical vapor deposition (CVD). For products on PET substrates, it is transferred to the polyethylene terephthalate polymer (PET) substrate using a wet transfer process. Its quality, shape, size and applications make it a benchmark product in the graphene market. Graphene Film Transparency: > 97% Coverage: > 95% Thickness (theoretical): 0.345 nm FET Electron Mobility on Al2O3: 2000 cm2/Vs Hall Electron Mobility on SiO2/Si: 4000 cm2/Vs Sheet Resistance: 580±50 Ohms/sq (1cm x 1cm) Grain size: Up to 10 μm PET Substrate Thickness: 175μm
