摘要：

We report the first Hall effect measurements on K and Rb doped single crystals of C60. The temperature dependence of the Hall coefficient RH for each material and the variation in RH between the two materials can be accounted for solely by the variations in lattice constant, yielding a universal relationship of RH versus lattice constant for the alkali-doped C60 systems. The results are interpreted in the context of a strongly disordered system in which the Hall coefficient is sensitive to disorder broadening at the Fermi energy. © 1995 The American Physical Society.
