Abstract

Using ab initio quantum chemical calculations, it was shown that the topologically determined energy levels decrease the energy gap at EF. It was demonstrated in examples that the presence or lack of five- and sevenfold rings are not sufficient for the existence or non-existence of electronic states at the Fermi level within tight binding approximation.
