摘要: Although small (spatially compact) bipolarons readily localize, large (like polarons) can be mobile. As such, are a suitable basis for bipolaronic superconductivity. However, only form in multidimensional ionic solids if the static dielectric constant greatly exceeds twice optical constant. The formation as well normal-state and superconducting properties of appear consistent with observations high-temperature superconductors.
