ARPES insight into the electronic structure of graphene/Co interface. (a) ARPES data taken near the K-point from well-oriented graphene on Co(0001) at room temperature, using 40 eV photons with s + p polarization. (b) Structure of graphene in momentum space; the line schematically indicates the direction of measurements. (c) ARPES insight into the minicone at EF obtained with 28 eV photons. (d) ARPES constant-energy maps of the minicone.
