Outline of Final Research Achievements

Graphene is a single-atom-thick sheet of carbon. Resonance Raman spectroscopy has been widely used to study optical properties of graphene. A theoretical analysis of Raman spectra gives us rich information on physical properties and sample characterization of graphene. In this study, we show optical properties of monolayer, bilayer, and trilayer graphene from a theoretical analysis of Raman spectra by calculating Raman intensity of graphene. The results provide a fingerprint for characterization of graphene by resonance Raman spectroscopy. For example, we show that stacking structure of trilayer graphene is characterized by M band in Raman spectra of trilayer graphene.
