Method for transferring graphene by attaching removable frame to protective layer applied on a sample containing graphene monolayer
A method of transferring graphene onto a target substrate having cavities and/or holes or onto a substrate having at least one water soluble layer is disclosed. It comprises the steps of: applying a protective layer (4) onto a sample comprising a stack (20) formed by a graphene monolayer (2) grown o...

| description | A method of transferring graphene onto a target substrate having cavities and/or holes or onto a substrate having at least one water soluble layer is disclosed. It comprises the steps of: applying a protective layer (4) onto a sample comprising a stack (20) formed by a graphene monolayer (2) grown on a metal foil or on a metal thin film on a silicon substrate (1); attaching to said protective layer (4) a frame (5) comprising at least one outer border and at least one inner border, said frame (5) comprising a substrate and a thermal release adhesive polymer layer, the frame (5) providing integrity and allowing the handling of said sample; removing or detaching said metal foil or metal thin film on a silicon substrate (1); once the metal foil or metal thin film on a silicon substrate (1) has been removed or detached, drying the sample; depositing the sample onto a substrate (7); removing said frame (5) by cutting through said protective layer (4) at said at least one inner border of the frame (5) or by thermal release. |
