Prediction of inorganic superconductors with quasi-one-dimensional
crystal structure    [PDF]

L. M. Volkova, D. V. Marinin

Models of superconductors having a quasi-one-dimensional crystal structure based on the convoluted into tube Ginsburg sandwich, which comprises a layered dielectric - metal - dielectric structure, have been suggested. The critical crystal chemistry parameters of the Ginsburg sandwich determining the possibility of emergence of superconductivity and the Tc value in layered high-Tc cuprates, which could have the same functions in quasi-one-dimensional fragments (sandwich-type tubes), have been examined. The crystal structures of known low-temperature superconductors, in which one can mark out similar quasi-one-dimensional fragments, have been analyzed. Five compounds with quasi-one-dimensional structures, which can be considered as potential parents of new superconductor families, possibly, with high transition temperatures, were suggested. The methods of doping and modification of these compounds were provided.
