A theoretical quest for high temperature superconductivity on the example of low-dimensional carbon structures

Abstract: High temperature superconductivity does not necessarily require correlated electron systems with complex competing or coexisting orders. Instead, it may be achieved in a phonon-mediated classical superconductor having a high Debye temperature and large electronic density of states at the Fermi level in a material with light atoms and strong covalent bonds. Quasi-1D conductors seem promising due to the Van Hove singularities in their electronic density of states. In this sense, quasi-1D carbon structures are go… Show more

“…We used a DFT method to improve quasi-1D superconducting carbon structures (Figure 9). Starting from (4,2) carbon nanotubes we reduced the nanotubes to a loop, opened it to form chains, optimized bond length and bend structure, and formed a new type of closed carbon loop that has a T c of 115 K [37].…”

“…Отметим, что, помимо изучения собственно карбина, интерес исследователей все чаще привлекают более сложные (композитные) структуры: различные комбинации углеродных цепочек [5,11,27]; карбин, соединяющий графеновые наноленты [4,8,9]; карбин, встроенный в УНТ [3,14]. При этом, естественно, встает вопрос об учете взаимодействия карбина с контактирующими объектами.…”
