| Outline of Final Research Achievements |
π-electronic materials, such as conjugated polymers and graphene, have been investigated for potential applications to various (opto)electronic devices. For clarification of the electronic states under application of voltage, we have measured the Raman scattering spectra of conjugated polyerms and single-layer graphene doped with ionic-liquid doping devices. For the conjugated polymers, not only changes of the vibrational Raman signals but also changes of the Raman signals reflecting the electronic states were revealed and analyzed. For single-layer graphene, the behavior of the coupling between lattice and electrons was clarified.
