WebThe vacancy–interstitial pair is called a Frenkel defect and the vacancy pair a Schottky defect, as shown in Figure 6.6. Interstitials are much more common in ionic structures than metallic structures because of the large ‘holes’ or interstices that are available. Sign in to download full-size image Figure 6.6. WebA Schottky defect is a type of point defect in a crystal lattice named after Walter H. Schottky. In non-ionic crystals it means a lattice vacancy defect. In ionic crystals, the defect forms when oppositely charged ions leave their lattice sites, creating vacancies. These vacancies are formed in stoichiometric units, to maintain an overall ... grammar school registration birmingham
