Abstract
A simple but self-consistent scheme is proposed for studying the electronic structure of graphite acceptor compounds (GAC). The basic concept of the computor renormalization group (CRG) is applied in simplifying the interactions between graphite and the intercalants, and a “pseudo-atom” is used to simulate the intercalant molecule. This model enables us to study different IC 8 type GAC in the same program, the extended Hückel energy band method is developed and the resulting band structures and Fermi surface properties of GAC (FeCl 3, AsF 5) thus obtained are discussed and compared with the present data.
