Electric capacitance as nanocondensers in zigzag nanographite ribbons and zigzag carbon nanotubes
Electronic states in nanographite ribbons with zigzag edges and zigzag carbon nanotubes are studied using the extended Hubbard model with nearest neighbor Coulomb interactions. The nearest Coulomb interactions stabilize electronic states with the opposite electric charges separated and localized along both edges. Such states are analogous as nanocondensers. Therefore, electric capacitance, defi...

متن کاملCalculations of Electric Capacitance in Carbon and BN Nanotubes, and Zigzag Nanographite (BN, BCN) Ribbons
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 opposite electric charges separated along both edges are analogous as nanocondensers. Therefore, electric capacitance, defined using a relation of polarizability, is calculated to examine nano-functionalities. We find...
متن کاملAdsorption and migration of carbon adatoms on zigzag carbon nanotubes
Using density-functional tight-binding and ab initio methods we study the adsorption and migration of carbon adatoms on surfaces of single-walled zigzag carbon nanotubes. We demonstrate that the adatoms form strong covalent bonds with the nanotubes and that the migration is strongly anisotropic. The adatom adsorption energy and migration barrier depend on the nanotube diameter and chirality. Th...
متن کاملTransport suppression in polymer-doped zigzag carbon nanotubes
The conductance of zigzag carbon nanotubes in the presence of grafted polymers attached to their walls is investigated. A theoretical study of the dependence of the transport on the nature of the molecule and on the concentration of attached structures is presented. The attached structures are shown to lead to the formation of resonant states trapping the electronic carriers and suppressing the...
