Abstract
Remarkable features of observed resistivity in higher stage graphite intercalation compounds are discussed by the theory recently developed by Inoshita and Kamimura. It is shown that the existence of two inequivalent electron pockets of cylindrical Fermi surface gives rise to the T 2-like temperature dependence in the resistivity. The calculated room temperature resistivity is 8.6 × 10 −6Ω cm for C 24K which is of the order of copper, and it can be ascribed to high Fermi velocity. Finally, it is suggested that the existence of a minimum in the observed resistivity-versus-stage curve is due to a variation of the charge distribution from layer to layer.
