Multilayer Graphene (10 mm x 10 mm)

Multilayer Graphene on SiO₂/Si, Quartz or PET (non AB Bernal stacking) - Processed in Clean Room Class 1000

The bilayer and trilayer graphene product consists of CVD layers produced by multiple transfer on a SiO2/Si, Quartz or PET substrate. Lower sheet resistance values can be obtained when compared to monolayer samples.
