| Research Abstract |
Carbon nanotube is a roll-up graphene sheet into a cylinder. Depending on the diameter and the way to roll, we get many different structures of the nanotube. In particular, depending on the diameter or the structure of the carbon nanotube, the electronic property of a carbon nanotube shows either metallic or semiconducting. Raman spectroscopy, which measures inelastic scattering of light, is a powerful tool to measure the structure and physical properties of carbon nanotubes. In this 5 years project, we published about 70 papers in which we theoretically propose new techniques of spectroscopy such as (1) gate modulated Raman spectroscopy and (2) coherent phonon spectroscopy and (3) exciton photophysics in a strong collaboration with experimental group in the world.
