Abstract

A process for exfoliating graphene, includes a step of irradiating a first substrate comprising graphene on its surface, with a helium or hydrogen plasma containing ions of energy comprised between 10 and 60 eV. A process for fabricating graphene on the surface of a second substrate, comprising the exfoliating process.
