Superconductivity and the grand periodic table of the chemical elements
Warsaw University, Faculty of Chemistry, Pasteura 1, Warszawa 02-093, Poland
Existence of the various families of superconducting materials and their TC values are rationalized within a simple model. "Magic ground electronic state" of superconducting matter is assumed to originate from the nontrivial avoided crossing between the electronic levels of the component chemical species, which enter the binary backbone of the multinary materials. Novel families of superconducting materials, particularly those based on fluoride and hydride anions, are predicted. Superconductivity is discussed in a broad framework including metallization of nonmetals and semiconductors, influence of the external pressure on the Peierls distortion, and dynamics of nuclear motion of the localized/delocalized mixed-valence species (molecular and in the extended phases).
