The Schottky defect and its consequences

The video tutorial explains vacancy defects in ionic compounds, focusing on Frenkel and Scotkey defects. It details the Scotkey defect, where equal numbers of cations and anions are missing, creating vacancies that maintain electrical neutrality. The defect is common in compounds with high coordination numbers and small ionic size differences. The tutorial also discusses the consequences of Scotkey defects, such as decreased density and stability of the crystal.
