| Outline of Final Research Achievements |
The effect of e-beam irradiation in absorption and Raman spectra have been measured. By the irradiation of e-beam to SWNTs thin films, the intensity of Raman D-mode increases which is connected to defects increase, and the peak energy of IR absorption bands shift to the higher energy side. The peak energy is proportional to the inverse of G/D ratio. These results indicate that the effective SWNT length decrease by introduced defects, and the origin of infrared band is due to the Plasmon resonance of finite-effective-length SWNT, often called antenna effects.
