Method for transferring graphene by attaching removable frame to protective layer applied on a sample containing graphene monolayer

Abstract

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 () onto a sample comprising a stack () formed by a graphene monolayer () grown on a metal foil or on a metal thin film on a silicon substrate (); attaching to said protective layer () a frame () comprising at least one outer border and at least one inner border, said frame () comprising a substrate and a thermal release adhesive polymer layer, the frame () providing integrity and allowing the handling of said sample; removing or detaching said metal foil or metal thin film on a silicon substrate (); once the metal foil or metal thin film on a silicon substrate () has been removed or detached, drying the sample; depositing the sample onto a substrate (); removing said frame () by cutting through said protective layer () at said at least one inner border of the frame () or by thermal release.
