Monolayer Graphene on Thin Film Cu on Sapphire (2" wafer)


Monolayer Graphene on Thin Film Cu on Sapphire (2" wafer)


Monolayer Graphene on on Thin Film Cu on Sapphire (2" wafer)- Processed in Clean Room Class 1000

Our monolayer graphene on Thin Film Cu deposited on a 2" diameter sapphire substrate is a 2D material produced by CVD. This product aims to meet wafer scale integration requirements to build uniform graphene devices in a fashion compatible with current industrial fabrication methods. This product is ready to be transferred by electrochemical delamination or dry methods since the sapphire substrate is robust enough to withstand mechanical damage, preventing Cu from tearing and wrinkling.

    Frequently Asked Questions

    A: No. Graphene bottom layer has to be removed before transferring onto the desired substrate. Different methods can be used such as oxygen plasma, Reactive Ion Etching (RIE) or chemical reactants such as diluted HNO3.

    A: We recommend to keep the samples in vacuum or inert atmosphere in order to avoid copper oxidation.

    A: The main orientation is <100>.
