Metallic and Insulating States in One-Dimensional and 2-Dimensional C-60-Polymers
Variations in the band structures of the one- and two-dimensional C-60-polymers are studied, changing conjugation conditions. We investigate the linear, rectangular, and triangular polymers, using a tight binding model with electron-phonon interactions. We find that electronic structures change among direct-gap insulators and the metal, depending on the degree of conjugations in the linear and rectangular polymers. The triangular polymer changes from the indirect gap insulator to the metal as the conjugations increase. High pressure experiments could observe such pressure-induced metal-insulator transitions.
