| 摘 要： | By preparing a field-effect transistor (FET) on C60 single crystal, Sch鰊 et al.[1] realized the hole-doped C60 and observed the superconductivity at 52 K. After CHBr3 molecules were intercalated into the crystal, the transition temperature increased up to 117 K[2]. This finding made the fullerite to be one of the highest-Tc superconductivity materials. In order to clarify the mechanism for the increase of Tc from 52 K to 117 K, the studies of the crystal structure, the density of electr…
