Abstract
A method for determining the Avogadro constant using samples of polygraphene made up of multiple layers of graphene is studied. The properties, and methods of producing, monitoring the crystal lattice quality, and determining the geometric parameters of the new materials, graphene and polygraphene, are examined. The method proposed by Fraundorf for creating fractional units of mass and amounts of the material with the aid of a polygraphene hexahedron is modified. The precision of the polygraphene prism technique is found to be low and a method for determining the Avogadro constant using a sample of highly oriented pyrolitic graphite with a high degree of chemical and isotopic purity offers more promise.
