Abstract

Employing previously published experimental data, we analyse the enhanced conductivity of the heterostructure comprising yttria-stabilised zirconia (YSZ) and SrTiO3. We confirm that the heterostructure's conductivity arises from SrTiO3, and we conclude that it is exclusively ionic below T ∼ 540 K. The calculated excess conductance from space-charge layers is found to be negligible.
