Bond Distortions in Armchair Type Single Wall Carbon Nanotubes
N. Sunel, E. Rizaoglu, K. Harigaya +1
The energy band gap structure and stability of (3,3) and (10,10) nanotubes have been comparatively investigated in the frameworks of the traditional form of the Su-Schrieffer-Heege…
Calculations of Electric Capacitance in Carbon and BN Nanotubes, and Zigzag Nanographite (BN, BCN) Ribbons
Kikuo Harigaya
Electronic states in nanographite ribbons with zigzag edges are studied using the extended Hubbard model with nearest neighbor Coulomb interactions. The electronic states with the…
Spin dependent transport of ``nonmagnetic metal/zigzag nanotube encapsulating magnetic atoms/nonmagnetic metal'' junctions
Satoshi Kokado, Kikuo Harigaya
Towards a novel magnetoresistance (MR) device with a carbon nanotube, we propose ``nonmagnetic metal/zigzag nanotube encapsulating magnetic atoms/nonmagnetic metal'' junctions. We…
Electronic Properties of Topological Materials: Optical Excitations in Moebius Conjugated Polymers
Kikuo Harigaya
Electronic structures and optical excitations in Moebius conjugated polymers are studied theoretically. Periodic and Moebius boundary conditions are applied to the tight binding mo…
A Theoretical Study on Spin-Dependent Transport of "Ferromagnet/Carbon Nanotube Encapsulating Magnetic Atoms/Ferromagnet" Junctions with 4-Valued Conductances
Satoshi Kokado, Kikuo Harigaya
As a novel function of ferromagnet (FM)/spacer/FM junctions, we theoretically investigate multiple-valued (or multi-level) cell property, which is in principle realized by sensing…
