The
search for new nanostructural topologies composed of elemental
carbon is driven by technological opportunities as well as the need
to understand the structure and evolution of carbon materials formed
by planetary shock impact events and in laboratory syntheses. We describe
two new families of diamond-graphene (diaphite) phases constructed
from layered and bonded sp<sup>3</sup> and sp<sup>2</sup> nanostructural
units and provide a framework for classifying the members of this
new class of materials. The nanocomposite structures are identified
within both natural impact diamonds and laboratory-shocked samples
and possess diffraction features that have previously been assigned
to lonsdaleite and postgraphite phases. The diaphite nanocomposites
represent a new class of high-performance carbon materials that are
predicted to combine the superhard qualities of diamond with high
fracture toughness and ductility enabled by the graphitic units and
the atomically defined interfaces between the sp<sup>3</sup>- and
sp<sup>2</sup>-bonded nanodomains.
