Abstract
There are topologically determined energy levels concentrated around t he Fermi level. Graph theory is used to estimate the density of states near the Fermi level (E(F)) of amorphous carbon (a-C) structure. With in F the ab initio Hartree-Fock calculations these states have lower e nergies than E(F), but they remain the highest occupied states in the electronic density of states.
