Patent ID: 8906784

Claim:
Method of manufacturing a structure comprising at least one modified semiconducting graphene layer, the modified graphene layer comprising a band gap between 0.2 eV and 1.8 eV, measured by scanning tunneling spectroscopy, and with a dispersion of electronic states, observed by Angle Resolved PhotoEmission Spectroscopy (ARPES or ARUPS), the dispersion of electronic states being either a valency band forming a Dirac cone or a linear dispersion of electronic states, the modified graphene layer being present on a substrate, comprising the following steps: supply of an initial structure comprising at least one non-metallic substrate capable of supporting a graphene layer, formation of a graphene layer on the substrate, wherein the graphene layer covers the totality of a surface of the substrate, hydrogenation of the initial structure by exposure to atomic hydrogen, to obtain the modified graphene layer, with an exposure dose between 100 Langmuirs and 4000 Langmuirs, namely between 13 mPa·s and 533 mPa·s.
