Highly stable two-dimensional graphene oxide: Electronic properties of its periodic structure and optical properties of its nanostructures Project supported by the National Key Research and Development Program of China (Grant No. 2017YFA0303600) and the National Natural Science Foundation of China (Grant Nos. 11474207 and 11374217). |
(color online) (a) Electronic band structures of C2O. Dotted line represents Fermi level. (b) Density of states (DOS) and the partial densities of states (PDOSs) of C2O. There are two identical O atoms, two identical C1 atoms, and two identical C2 atoms in the primitive cell of C2O, and O atom, C1 atom, C2 atom are shown in PDOSs, Fermi level is indicated by the dashed line. |
