Monolayer Graphene on Quartz

Monolayer Graphene on Quartz - Processed in Clean Room Class 1000

Our monolayer graphene on Quartz (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.
