Abstract

For provides a superconducting material comprising highly chemically stable Fullerene carbon molecules having a relatively high transition temperature and high chemical stability, CFullerene molecules having stronger electron-lattice interaction than that of CFullerene molecules are used, in order to polymerize the CFullerene molecules into a one-dimensional chain, Cis incorporated in a gap of a material having a large band gap between a valence band and a conduction band, thereafter, electrons or positive holes are injected into the obtained CFullerene chain polymer via an electric field application for phase transition to a superconductor.
