| Outline of Final Research Achievements |
The localized plasmon resonances are of particular interested because the observed phenomena drastically depend on various properties including geometry of nano-structures and excitation energy dispersions of carbon materials. Recently, we reported the plasmon resonance of clean CNT channels both single-walled and multi-walled CNTs. In these CNTs, the conventional carrier density (n) dependence (the square root of n) never been observed by chemical doping measurements. In the case of graphene, the carrier density dependence of plasmon resonances is theoretically expected from the fourth root of n (2D) to n to 0 power (1D) by decreasing confinement dimensions. Therefore, in this study, we will report the dimensionality dependence of plasmon resonance in graphene nano-ribbons fabricated from a single layer graphene.
