Monolayer Graphene on SiO₂/Si (4" Wafer) - Fully Covered：

Our monolayer graphene on SiO2/Si (4” Wafer, fully covered) is a bidimensional material produced by CVD and transferred to a circular substrate of Si/SiO2 (300nm) by a wet transfer process. We consider it to be a benchmark product in the graphene market - not only for its excellent quality, but also for its shape, size and number of applications.
