Monolayer Graphene Film on Quartz 4″ wafer


Monolayer Graphene Film on Quartz 4″ wafer are the subject of intense scientific research due to their unique electronic properties and have potential applications in microelectronics applications micro- and nano-electromechanical systems (MEMS and NEMS), in field effect transistors (FETs), and in  chemical and biological sensors among others.


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.
