Amorphous state of sp${}^2$ solid carbon

Abstract

Two-mode valence electron configuration of carbon atoms lays the foundation of the unique two-mode amorphous state of the monoatomic carbon solid. From the fundamentals of solid-state physics, sp${}^3$ and sp${}^2$ amorphous carbons are two different amorphous species characterized by conceptually different short-range orders, namely, groups of tetrahedrally bonded sp3 configured atoms and size-restricted sp${}^2$ graphene domains framed with heteroatom necklaces. Molecular character of sp${}^2$ amorphics is coherent with the reaction mechanism of the solid amorphicity in due course of the forced fragmentation.
