Method for transferring a graphene layer
Abstract:
A method transfers a graphene layer from a donor substrate onto a final substrate. The method includes: providing a metal layer on the donor substrate; and growing a graphene layer on the metal layer. The method also includes: laminating a dry film photo-resist on the graphene layer; laminating a tape on the dry film photo-resist; chemically. etching the metal layer, obtaining an initial structure that includes the tape, the dry film photo-resist and the graphene layer; laminating the initial structure on the final substrate; thermally realizing the tape, so as to obtain an intermediate structure that includes the dry film photo-resist, the graphene layer and the final substrate; removing the dry film photo-resist; and obtaining a final structure that includes the final substrate with a transferred graphene layer.
