摘要：

Electrical transport properties of alkali metal-doped C60 solids were studied. Single crystals obtained from a CS2 solution show a metallic temperature dependence of the resistivity from room temperature to superconducting transition temperatures T(c) for samples optimally doped with potassium or rubidium. The thermoelectric power of potassium- or rubidium-doped crystals has a negative value and shows metallic behavior in the temperature range T(c)-300 K. Based on this result we estimate the Fermi energy E(F) to be 0.30-0.35 eV for a potassium-doped crystal and 0.19-0.20 eV for a rubidium-doped crystal, assuming a three-dimensional free electron model.
