“…Hembram et al achieved a carbon-pure formation of the diamond via surface hybridization with GN [69]. GN multilayers (5-50 nm in thickness) were grown vertically onto a polished <110> textured polycrystalline diamond film via hydrogen plasma etching in a CVD chamber at~1300 • C. A fascinating analogy of the surface defects known for the diamond, the hybrid GN-diamond interface contains "interface defects" responsible for a strong photoluminescence signal.…”

Carbon nanomaterials with a different character of the chemical bond—graphene (sp2) and nanodiamond (sp3)—are the building bricks for a new class of all-carbon hybrid nanomaterials, where the two different carbon networks with sp3 and sp2 hybridization coexist, interacting and even transforming into one another. The extraordinary physiochemical properties defined by the unique electronic band structure of the two border nanoallotropes ensure the immense application potential and versatility of these all-carbon nanomaterials. The review summarizes the status quo of sp2 – sp3 nanomaterials, including graphene/graphene-oxide—nanodiamond composites and hybrids, graphene/graphene-oxide—diamond heterojunctions, and other sp2–sp3 nanocarbon hybrids for sensing, electronic, and other emergent applications. Novel sp2–sp3 transitional nanocarbon phases and architectures are also discussed. Furthermore, the two-way sp2 (graphene) to sp3 (diamond surface and nanodiamond) transformations at the nanoscale, essential for innovative fabrication, and stability and chemical reactivity assessment are discussed based on extensive theoretical, computational and experimental studies.

“…The configuration shown in Figure 2(b) agrees with the one predicted by Refs [7,34] as a transition state between an unreconstructed 1x1 phase and a fully reconstructed 2x1 phase. According to the literature, the most stable configuration for the (111) surface is a complete 2x1 reconstruction [7,10,[18][19][20]. Since the diamond surfaces used in this study are defect-free, our simulations suggest that other effects might be necessary to trigger a complete 2x1 reconstruction.…”

“…We started by selecting five different pristine diamond surfaces: (001), (013), (110), (113), and (111). These surfaces are selected because they are widely studied in several experimental and theoretical works for device applications [6,7,13,[18][19][20][24][25][26].…”

“…During the diamond crystal syntheses (powder or film), different exposed facets/surfaces can be created [8][9][10]. These diamond surfaces will have a different number of carbon dangling bonds, structural defects, and surface reconstructions [10,13,18,19]. Such features will have a direct impact on the hydrogenation patterns and on the resulting electronic and mechanical properties.…”

Carbon nanomaterials with a different character of the chemical bond – graphene (sp2) and nanodiamond (sp3) are the building bricks for a new class of all-carbon hybrid nanomaterials, where the two different carbon networks with the sp3 and sp2 hybridization coexist, interact and even transform into one another. The unique electronic, mechanical, and chemical properties of the two border nanoallotropes of carbon ensure the immense application potential and versatility of these all-carbon graphene – diamond nanomaterials. The review gives an overview of the current state of the art of graphene – diamond nanomaterials, including their composites, heterojunctions, and other hybrids for sensing, electronic, energy storage, and other applications. Also, the graphene-to-diamond and diamond-to-graphene transformations at the nanoscale, essential for innovative fabrication, and stability and chemical reactivity assessment are discussed based on extensive theoretical, computational, and experimental studies.
