Figure 4From: Graphene on ferromagnetic surfaces and its functionalization with water and ammonia Series of the ARPES spectra obtained on graphene/Ni(111), H 2 O/graphene/Ni(111), and NH 3 /graphene/Ni(111) along the Γ- K direction of the Brillouin zone. The amounts of water and ammonia were estimated as 0.5 of the ML. These data were collected with the photon energy of 75 eV.Back to article page
