Novel Electronic States in Graphene Ribbons -Competing Spin and Charge Orders-
Atsushi Yamashiro, Yukihiro Shimoi, Kikuo Harigaya +1
In a nanographene ring with zigzag edges, the spin-polarized state and the charge-polarized state are stabilized by the on-site and the nearest neighbor Coulomb repulsions, U and V…
Competition between spin and charge polarized states in nanographene ribbons with zigzag edges
Atsushi Yamashiro, Yukihiro Shimoi, Kikuo Harigaya +1
Effects of the nearest neighbor Coulomb interaction on nanographene ribbons with zigzag edges are investigated using the extended Hubbard model within the unrestricted Hartree-Fock…
Theoretical study on novel electronic properties in nanographite materials
Kikuo Harigaya, Atsushi Yamashiro, Yukihiro Shimoi +8
Antiferromagnetism in stacked nanographite is investigated with using the Hubbard-type model. We find that the open shell electronic structure can be an origin of the decreasing ma…
Magnetic Structure of Nano-Graphite Moebius Ribbon
Katsunori Wakabayashi, Kikuo Harigaya
We consider the electronic and magnetic properties of nanographite ribbon with zigzag edges under the periodic or Moebius boundary conditions. The zigzag nano-graphite ribbons poss…
The Hypergraphite: A possible extension of graphitic network
Y. Takagi, M. Fujita, K. Wakabayashi +4
We propose a class of networks which can be regarded as an extension of the graphitic network. These networks are constructed so that surface states with non-bonding character (edg…
