“…Its essence is that the injection of charge carriers from oriented carbyne to any dielectrics (including electron emission to vacuum) occurs with equal efficiency [10]. This result can't be explained in terms of classical band theory.…”

An attempt to simplify the approach to the problems of room-temperature superconductors was done. The key factor has been highlighted-a giant spin-orbit interaction as a result of specific geometry of crystal. Considering oriented carbyne as an example, it was shown that maximal value of SOC was attained in low-dimensional systems. A qualitative model of superconductivity in the localized phase with "pseudo-magnetic field" and "Rashba effective field" as parameters was presented. Their correlation was shown via geometry of electric microfields of crystal. Oriented carbyne was presented as localized phase of room-temperature superconductor and the recipe of its transformation to macroscopic superconductivity was given.

“…This charge distribution is typologically uncontroversial with the hexagonal order (on the right in Figure 2). Assumptions concerning the existence of some "built-in" field were put forward before with a view to possibly explain the abnormal injection emission capability [11]. Its source could be spin-charged solitons similar to those in conjugated polymers [13].…”

“…Forces that would have trilateral symmetry corresponding to the three nearest neighboring chains should exist between the chains. It is known from the experiments that highly ordered carbyne films as low as 20 Å thick have the same injection properties as films with the thickness of 1000 Å [11]. The particularity of the chain build-up technology is that the chains several atoms long precipitate in one pulse.…”

“…These are primarily electron diffraction and X-ray microanalysis data that showed an ideal hexagonal packing [5]. The indirect evidence of linear chains conservation was tunnel transparency of rather thick carbyne films as well as excellent repeatability of experiments on the charge carrier injection from carbyne films and injection current independence from the carbyne film thickness (from 20 to 1000 Å) [11]. Thus, if kinks do exist along the chains, they should not lead to a loss of long-range order of the chain.…”

Time-of-Flight Mass Spectrometry of Highly Ordered Carbyne

Matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometry was applied to a non-conven-tional object–highly ordered carbyne films. Mass spectra of both positive and negative ions were recorded in all tests. The spectra had a rather high number of hydrogen atom peaks and specific features indicative of hydrogen acting as a requisite stabilizer in the crystalline carbyne structure. A new model based on interchain dihydrogen bonds was proposed

“…Because of its dielectric properties, silicon oxide has long been used and considered as a passive, insulating component in the construction of electronic devices. In contrast, here we used it as a semi-conductor that emerged due to a unique capability of carbyne to inject carriers through any high energy barriers [3]. The latter manifest themselves as some effective barriers, which are signifi-cantly reduced.…”
