It begins with an overview of the atomic nature of matter and the forces that link atoms together in crystal lattice structures. It discusses the types of imperfections (or defects) that occur in the crystal...

... for diffusing atoms. However, such vacancies should form in a way that does not alter the charge of the oxide. Here, Schottky and Frenkel defects assist diffusion, as the cations diffuse through cationic vacancies and the anions diffuse through the anionic vacancies. The activation energies may differ for both...
