A theory of the interionic structure of graphite intercalation synthetic metals: Variations with respect to interactions and state

A statistical mechanical theory is developed and applied to study the structural effects that the thermodynamic state of alkali ions have on graphite intercalation compounds. The system considered is that of second stage Rb–graphite. Two-dimensional diffraction patterns are computed and compared with experimental measurements. Sensitivity to model parameters are considered. A low order density functional expansion is found to adequately describe the interionic structure of the system modeled as a two-dimensional one component plasma in an anisotropic external field.
