Edge states of zigzag graphene nanoribbons with B and N doping at edge atoms
Tomoaki Kaneko, Kikuo Harigaya
Using a tight binding model, we theoretically study the electronic properties of zigzag boron-carbon-nitride (BCN) nanoribbons where the outermost C atoms of zigzag graphene nanori…
Dependence of atomic arrangement on length of flat bands in zigzag BC2N nanoribbons
Tomoaki Kaneko, Kikuo Harigaya
We theoretically study the electronic properties of BC2N nanoribbons with zigzag edges using a tight binding model. We show that the zigzag BC2N nanoribbons have the flat bands and…
Appearance of Flat Bands and Edge States in Boron-Carbon-Nitride Nanoribbons
Tomoaki Kaneko, Kikuo Harigaya, Hiroshi Imamura
Presence of flat bands and edge states at the Fermi level in graphene nanoribbons with zigzag edges is one of the most interesting and attracting properties of nanocarbon materials…
Intrinsic giant Stark effect of boron-carbon-nitride nanoribbons with zigzag edges
T. Kaneko, K. Harigaya, H. Imamura
Electronic properties of zigzag boron-carbon-nitride (BCN) nanoribbons, where the outermost C atoms on the edges of graphene nanoribbons are replaced by B or N atoms, are theoretic…
Anisotropic Magnetoresistance Effects in Fe, Co, Ni, Fe_4N, and Half-Metallic Ferromagnet: A Systematic Analysis
Satoshi Kokado, Masakiyo Tsunoda, Kikuo Harigaya +1
We theoretically analyze the anisotropic magnetoresistance (AMR) effects of bcc Fe (+), fcc Co (+), fcc Ni (+), FeN (-), and a half-metallic ferromagnet (-). The sign in each (…
Electron density distribution of bilayer nanographene and band structures of boron-carbon-nitride systems
Kikuo Harigaya, Hiroshi Imamura
Bilayer graphene nanoribbon with zigzag edge is investigated with the tight binding model. Two stacking structures, alpha and beta, are considered. The band splitting is seen in th…
