摘要: Based on first principles calculation, the electronic properties of graphene metal (Ti, Ca, Ni, Mn, Co, Fe, Cr, K) modified SiO2 substrate have been studied. The results binding energies supported indicate that atoms are adsorbed more stably O surface than Si substrate, and is very substrate. band structures similar with suspending when deposited Co surface, but change obviously effect decorated Fe atoms. Interesting, a semi-metal structure 1-2 eV gap in spin-up state will occur magnetic surface.
