Query: Critical Temperature Tc versus Charging Energy Ec in
  Molecular-Intercalated Fullerenes   We study the recently discovered 117-Kelvin superconducting system C60/CHBr3
of the field-effect transistor and propose a possibility that the intercalation
molecule CHBr3 plays a role of an electric capacitor in the C60 fullerene
superconductor, which contrasts rather with an expectation that the
intercalation molecule in that system acts as simple spacer molecule.
Estimating the critical temperatures Tc for several C60/X (X: intercalation
molecule), we suggest searching for intercalation molecules with large
molecular polarizabilities, in order to attain higher Tc in the synthesis of
fullerene superconductors and to more systematically develop high Tc
superconducting electronic devices.
