Abstract

During the past several years the graphite intercalation compounds (GIC) have aroused a great deal of interest in the field of solid state physics. In the present paper a review is given on two topics on the electronic properties of GIC about which intensive studies have been recently made. These are the electronic structures of higher stage GIC and the mechanism of superconductivity in the first stage alkali-metal GIC. In the first part of the present paper (Part I) the first principles non-empirical band structure calculation of higher stage GIC recently done by OHNO, SHIMA and KAMIMURA [1] is presented, with a particular emphasis being laid on the determination of the non-homogeneous charge distribution along the c-axis. In the second part of the present paper (Part II) the theory of superconductivity of the first stage alkali-metal GIC, C8M, recently developed by TAKADA [2] is presented. We clarify the long-standing question on why C8M become superconductors, although neither graphite nor the alkali metals are superconducting.
