| 英文摘要 | surface functionalization of epitaxial graphene overlayers on 6h-sic(0001) has been attempted through thermal reactions in nh3. x-ray photoelectron spectroscopy and micro-region low energy electron diffraction results show that a significant amount of n is present at the nh3-treated graphene surface, which results in strong band bending at the sic surface as well as decoupling of the graphene overlayers from the substrate. the majority of the surface n species can be removed by annealing in vacuum up to 850 a degrees c, weakening the surface band bending and resuming the strong coupling of graphene with the sic surface. the desorbed n atoms can be attributed to the intercalated species between graphene and sic. low temperature scanning tunneling spectroscopy and density functional theory simulations confirm the presence of n dopants in the graphene lattice, which are in the form of graphitic substitution and can be stable above 850 a degrees c. this is the first report of simultaneous n intercalation and n doping of epitaxial graphene overlayers on sic, and it may be employed to alter the surface physical and chemical properties of epitaxial graphene overlayers. |
