Investigation of the Mechanism of Electric Conductivity of Strontium Bismuthate Sr₆Bi₂O₁₁

Abstract

The paper presents data on the temperature dependence of the conductivity of strontium bismuthate Sr6Bi2O11. It is shown that the temperature dependence of conductivity cannot be described in the framework of existing models. It was found that at a temperature of about 400 K a change in the radius of localization of the charge carrier is observed.
