| Outline of Final Research Achievements |
Peanut-shaped fullerene (C60) polymers, a new type of nanocarbons, have been created by electron beam irradiation to C60 crystals. They can be formed through the generalized Stone-Wales transformation between adjacent C60 molecules. A wide variety of intriguing phenomena
including the anomalous low-temperature resistivity and the photoexcited carrier relaxation
have been observed, while a unified interpretation has not been settled. In the present study, the electronic, phononic, and optical properties of solids as well as C60 polymers have been investigated theoretically. A fundamental understanding of them has been obtained. Ultrafast relaxation dynamics of electron and phonon in solids has been investigated as well.
