摘要：

This paper deals with the dependence of ionic and electronic conductivities as a function of concentration and spacing of interfaces. It pays particular attention to the alteration of the degree of mixed conductivity on account of a variation in point defect chemistry in space charge regions and in the interfacial core region. Of particular relevance is the size effect on the standard chemical potentials, which can be very different for ions and electrons corresponding to the degree of delocalisation.
