<p>Heteronuclear solid state materials characterized by temperature dependent electronic structure instability with respect to some of pertinent phonon modes that drive said materials from metal-like adiabatic electronic ground state with high-symmetry equilibrium nuclear geometry of corresponding crystal structure into intrinsic nonadiabatic or antiadiabatic geometrically degenerate electronic ground state that is stabilized at distorted nuclear geometry characteristic by fluxional configuration of the atoms in respective phonon modes are superconductors. The methods for the designing, physical parameters-determining, and targeted synthesis of these heteronuclear solid state materials have also been disclosed.</p> |
