Complex oxides: high temperature defect chemistry vs. low temperature defect chemistry

Joachim Maier2003-01-01Physical Chemistry Chemical Physics

The contribution addresses the bridge between high temperature chemistry at which thermodynamic defect equilibrium with neighbouring phases can be assumed, and low temperature physics in which usually only electronic carriers behave reversibly. An optimised quenching procedure is discussed to obtain profile-free repro…
