“…Among these, the idea that it is the high electric fields (ϳ1 V͞Å) present at the tube tips that keeps the tubes open is the most appealing [20]. However, detailed ab initio investigations of this effect show that the high electric field alone cannot stabilize the open-tube geometry, even for very narrow tubes [17,21]. Similarly, other reasons such as a temporary saturation of the dangling bonds with hydrogen, or the presence of large thermal gradients, can likewise be eliminated [20].…”

“…A section of the potential-energy distribution (corresponding to an electrode separation D of 4 nm) is represented in the left part of figure 2. The nanotube acts essentially as a metallic cylinder, so its interior is nearly at a constant potential [17][18] [19]. In all cases, there is a significant contribution at the Fermi level (due to a higher transmission probability and a non-zero supply function).…”

We present simulations of field emission from carbon nanotubes, using a transfer-matrix methodology. By repeating periodically a basic unit of the nanotubes in the region preceding that containing the extraction field, specific band-structure effects are included in the distribution of incident states, i.e. those entering the field region. The structures considered are the metallic (5,5) and the semiconducting (10,0) single-wall carbon nanotubes. The total-energy distributions of incident states show the gap of the (10,0) and the expected flat region for the (5,5) nanotube. The field-emitted electron energy distributions contain peaks, which are sharper for the (10,0) structure. Except for peaks associated with van Hove singularities in the distribution of incident states or with the Fermi level in the case of a metallic structure, all peaks are shifted to lower energies by the electric field.

“…Carbyne is the linear allotrope of carbon. To date, carbyne, as an object of research, leaves behind graphene by the number of works, due to its unique physical, mechanical, and chemical properties [1][2][3][4], as well as due to promising applications [5][6][7][8][9][10]. The possibility of realization of these unusual functional properties is significantly depending on the strength and elasticity of carbyne.…”

The results of the high-field technique for obtaining and testing the carbyne strength in situ are presented. By using molecular dynamics simulation and ab initio calculations, a comprehensive analysis of the results is executed. High-field technique for experimental measurement of the carbyne strength in situ is briefly described. It is shown that the technique used gives a lower estimation for strength of carbyne, which equals 251 GPa at T = 77 K. This value is close to the strength 7.85 nN (250 GPa) of contact atomic bond between carbyne and graphene sheet, from which the monatomic chain is pulled. The strength of carbyne itself is determined by strength of an edge atomic bond and it is ≈ 12.35 nN (393 GPa) at T = 0 K. For carbynes containing more than 10 to 12 atoms, the coefficient of elasticity (k Y = 145.40 nN) and the elastic modulus (Y = 4631 GPa) are ascertain.
