Abstract
A method for transferring a graphene layer from a metal substrate to a second substrate is provided comprising: providing a graphene layer on the metal substrate, adsorbing hydrogen atoms on the metal substrate by passing protons through the graphene layer, treating the metal substrate having adsorbed hydrogen atoms thereon in such a way as to form hydrogen gas from the adsorbed hydrogen atoms, thereby detaching the graphene layer from the metal substrate, transferring the graphene layer to the second substrate, and optionally reusing the metal substrate by repeating the aforementioned steps.
