Electrical superconductivity of a carbon compound formed by a one-electron covalent bond of atoms

This paper presents quantitative data on the key parameters of the atomic structure and valence electron energy spectrum of a newly synthesized carbon compound formed by one-electron covalent bonds between atoms. An analysis of these data indicates that this substance can undergo a superconducting transition. Quantitative estimates lead to the conclusion that such a transition can be realized under external pressures of ≈10–2 GPa, with a critical temperature of Tc ≈ 120 K, which is an order of magnitude higher than the average value characteristic of classical metals. It is shown that similar conditions for a superconducting transition can also be realized in a substance with particle sizes R ≤ 10–7 m due to internal (capillary) pressure.
