Query: Essential Properties of Fluorinated Graphene and Graphene Nanoribbons   A systematic study is conducted on the fluorination-enriched essential
properties of 2D graphene and 1D graphene nanoribbons using the
first-principles method. The combined effects, which arise from the significant
chemical bonds in C-C, F-C and F-F bonds, the finite-size quantum confinement,
and the edge structure, can greatly diversify geometric structures, electronic
properties and magnetic configurations. By the detailed analyses, the critical
orbital hybridizations in determining the essential properties are accurately
identified from the atom-dominated energy bands, the spatial charge
distributions, and the orbital-projected density of states. The top-site F-C
bonds, with the multi-orbital hybridizations, create the non-uniform buckled
honeycomb lattice. There exist the C-, F- and (C, F)-dominated energy bands.
Fluorinated graphene belongs either to the p-type metals (with/without the
ferromagnetic spin arrangement) or to the large-gap semiconductors (without
magnetism), depending on the concentration and distribution of adatoms.
Specially, fluorinated graphene nanoribbons, with armchair/zigzag edge,
presents five kinds of spin-dependent properties, covering the non-magnetic and
ferromagnetic metals, non-magnetic semiconductors, and anti-ferromagnetic
semiconductors with/without the spin splitting. The various band-edge states in
2D and 1D systems appear as the rich and unique structures in density of
states. Part of theoretical predictions are consistent with the experimental
measurements, and the others are worthy of the further examinations. Also, the
fluorination-created diverse properties clearly indicate the high potentials in
various applications that will be discussed in detail, e.g., electronic and
spintronic nanodevices.
