Abstract
A method is used for releasing a graphene layer from a substrate. A graphene layer is first formed on a surface of a first substrate. A metal layer is then formed on a surface of the graphene layer. A pulling force is then applied to the metal layer to detach the graphene layer from the first substrate. The released graphene layer is bonded by intermolecular force onto a surface of a second substrate separate from the first substrate or onto a surface of a bonding layer formed on the surface of the second substrate. The metal layer is then removed, by for example, etching.
