摘要：
The systematic study of the ionic transport properties of epitaxial Y2Zr2O7 films with defective fluorite structure reveals an enhanced oxygen vacancy conductivity at the interface between the films and the MgO(110) substrate, which is characterized by a high density of misfit dislocations. This beneficial effect is discussed in terms of space-charge and mobility effects.
