This tutorial gives an introduction into the equilibrium defect chemistry of crystalline solids with emphasis on metal oxides. Topics discussed include lattice and electronic defects, defect notations, defect structures, point defect concentrations in dependence of temperature, partial pressure and doping level, and the correlation between defect chemistry and transport properties of materials. Also covered are underlying concepts such as structure elements versus building blocks, size exclusion effect, chemical potentials of ionic and electronic defects, virtual versus true chemical potentials, etc. Attendees are invited to present and discuss problem cases encountered in their own research practice.
