ナノカーボンの共鴫ラマン分光

抄録

Carbon nanotubes and nano-graphite are called as nano-carbons made of graphene skeleton. Resonant Raman spectroscopy is a powerful tool to investigate the special electronic and phonon structures of nano-carbons. Although Raman spectroscopy has been used for characterizing carbon materials for long years, the origin of some weak Raman spectra is not always clearly understood. The recent progress of Raman spectroscopy has provided a new concept such as double resonance Raman theory for the undefined spectra observed not only in nano-carbon but also in conventional carbon materials. Especially single nanotube spectroscopy becomes a standard technique in which we measure with no-contact, at room-temperature and ambient pressure.
