Multilayer Graphene Nanoclusters: Structure, Electronic and Magnetic Properties

Abstract:

The data on atomic and electronic structure and some magnetic properties of graphite domains in activated carbon fibers (ACF) are presented. It has been established that graphite domains have nanometer sizes in all three dimensions, and consist of about three turbostratically stacked nanographenes. Such multilayer nanographene clusters (nanographites) are structural blocks of ACF and they are separated from each other by the micropores and/or sp³-amorphous carbon phase. From the data of magnetic methods of investigations, it follows that the density of states at the Fermi energy in nanographites is significantly larger than the value of that parameter in macroscopic graphite, which testifies the existence of edge π-electron states in them.
