Abstract
The thermodynamic point defect concentrations for both ionic (majority) as well as electronic (minority) charge carriers are considered for different types of heterogeneities appearing in ionically conductive solid materials systems. Particularly, the electrical conductivity is discussed for different types of composite electrolytes. Quantitative space charge arguments are shown to be able to explain a variety of different phenomena such as: unusual enhancement of ionic conductivity in two phase samples and in polycrystalline materials, additional conductivity effects in microsized systems; change from cationic to anionic conduction due to heterogeneous doping; simultaneous enhancement of n- and p-conductivity in different electrolyte/ alumina samples, catalytic effects in composite electrolytes as well as chemical interface effects.
