| Outline of Final Research Achievements |
Electrons or holes that are excited by light show unique properties of solid for low-dimensional materials. In this project, we first investigate circular dichroism of single wall carbon nanotube in which the optical absorption has different values for left-handed and right-handed circularly polarized light. Making the computor program based on the theory that we established, the degree of circular dichroism is calculated as a function of the chirality of nanotube which is directly compared with the experimental results. Further we discuss the optical absorption of the near-field at the top of metallic tip, which is used in tip-enhanced Raman spectroscopy. We also calculate the enhancement of electric field by dielectric multilayer in which the interference effect by many reflection is important for enhancing the electric field. We make a useful theory to calculate the enhancement of electric field. As a related topic, we also discussed helicity dependent Raman spectroscopy.
