Monolayer Graphene Film on Quartz 4″ wafer
Our monolayer graphene on Quartz 4” wafer, fully covered is produced by CVD and transferred to a circular substrate of Quartz (500 μm thickness) by a wet transfer process.
Its high quality and wide range of applications make it a benchmark product in the graphene market.
