Graphite jt-bands

The simplest model of the electronic structure of GICs can be obtained from the Jt-band structure of graphite on the basis of the Slonczewski-Weiss-McClure tight-binding model with the rigid band scheme. Here, the intercalate bands are superimposed on the graphite rc-bands, their relative... 

Each carbon atom in the graphite structure contributes 4 valence electrons, resulting in 16 energy bands, 4 of them Jt-bands (two bonding and two antibonding) on either side of the Fermi level. In AB-stacked graphite, the separation between the... 

Let us see if we can predict the modifications in energies of COs that should occur at some of the special points in the RFBZ as a result of intersheet interactions. Because three-dimensional Bernal graphite is symmetric for reflection through the plane of a hexagonal sheet, we continue to have a valid distinction between a and n COs. We expect intersheet interactions to be small, so we can take a perturbational approach. The interactions involving jt COs should be largest since p AOs project farthest from the plane, so we will restrict our attention to the n bands.
