Abstract

We propose an explanation for the high electrical conductivity of the ferroelectric strontium-barium niobate. As the temperature T approaches the ferroelectric transition T_c, the static dielectric constant ε₀ diverges when a soft mode occurs. This divergence of ε₀ reduces the donor binding energy and increases the effective Bohr radius of the donor. The electrons bound to the donors become unbound and the material becomes conductive.
