... carbon chains packed parallel to one another in hexagonal structures are oriented perpendicular to the substrate surface. In the carbon atom chains, each carbon atom is connected to the two nearest neighbors by the sp-1 bonds. Geometric characteristics of the two-dimensionally ordered linear-chain carbon nano-matrix is presented in Fig. ...

... straight carbon chain becomes unstable as it lengthens. A carbon chain with self-forming kinks (see Fig. 5) is a more stable system (energetically more favorable) than a straight carbon ...

... on the vibrating layer and the plasma ions will serve as the additional energizing factor controlling the local pattern formation and self-organizing of the nano-structures. Application of the inverse piezoelectric effect during the ion-assisted carbon pulse-plasma deposition can be provided through the deposited piezoelectric layer (see Fig. 15). The piezoelectric layer converts the released electric energy into mechanical acoustic oscillations that propagate through the substrate and growing nano-matrix. Applying an alternating current or radio frequency excitation to electrodes patterned on a piezoelectric material, generates an acoustic wave that propagates in the ...

... With taking into account that the 2D-LCC-based nano-matrix are acoustically sensitive nanomaterial, we propose use the predictive fine tuning the nanoarchitecture, vibrational characteristics and heteroatom-doping by using the surface acoustic wave (SAW)-based toolkit, [13]. In particular, we propose to use the technology of the carbyne-enriched nanomaterial growing onto acoustically excited piezoelectric-based substrates. ...
We propose to uncover new opportunities for predictive nano-sized energetic materials performance enhancement through manipulating by vibrational interactions, energy exchange as well as heat transfer enhancement within the reaction zones at nanoscale. The combination of multiple carbon nanostructured materials with various hybridizations within a single substance can uncover new unique properties. Due to a recent fundamental discovery the collective atomic vibrations, called phonon waves, manifested in transition domains of multilayer nanostructures, incorporation of self-organized arrays of metastable nanostructures are capable controlling vibrational interactions and energy exchange within the reaction zones at nanoscale. For using this phenomenon, we propose predictive incorporation into the nano-sized energetic material composition of various carbon-based allotropes, used as catalytic nano-additives, combined with assembling them by the self-organized arrays of differently hybridized low-dimensional nanocarbon promoters. For predictive combining of multiple differently hybridized nanocarbons within a single substance we propose to use the energy-driven initiation of the allotropic phase transformations in nanocarbon promoters by concurrent electron and ion irradiation. For fine tuning the collective atomic vibrations, nanoarchitecture and functionality of the mentioned arrays of differently hybridized nanocarbon promoters we propose using combination of a set of techniques: concurrent electron and ion irradiation, using the surface acoustic waves combined with heteroatom doping along with application external electromagnetic fields and using the data-driven nanoscale manufacturing approach.
We present a method of synthesis of sp-carbon allotropes or carbynes. Linear chains of carbon atoms are obtained from graphite placed in a joint field of laser plasma and arc discharge. The combined action of laser and arc discharge allows to create conditions for the formation of a variety of carbon allotropes, whose structural composition is governed by the interplay of external fields. The method may be employed in the mass production of sp- and sp²- hybridized carbon for the needs of possible applications in micro and nanoelectronics, biosensing.
