The Band Theory of Graphite NASA/ADS

The structure of the electronic energy bands and Brillouin zones for graphite is developed using the "tight binding" approximation. Graphite is found to be a semiconductor with zero activation energy, , there are no free electrons at zero temperature, but they are created at higher temperatures by excitation to a band contiguous to the highest one which is normally filled.

Carbon Structure of carbon allotropes | Britannica

Carbon Carbon Structure of carbon allotropes: When an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite. The crystal structure of diamond is an infinite threedimensional array of carbon atoms, each of which forms a structure in which each of the bonds makes equal angles with its neighbours.
