SrTi03:: a model electroceramic

It is shown that the defect chemistry of acceptor-doped SrTiO3 is understood in great detail, and that this permits the accurate description, not only of the equilibrium electronic and ionic conductivities, but also of non-equilibrium situations generated by electrical or chemical driving forces, and even of the quenched state. Recent investigations on internal and external boundaries provide astonishingly precise insights into the pertinent structure-property relations.
