In a schottky defect
WebSchottky defect is a type of point defect. It is a stoichiometric defect in which both cations and anions remain missing from their lattice site in equal numbers and hence … 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.

WebIn the so-called Schottky defect, an atom moves from the inside of the crystal to its surface, leaving behind an isolated vacancy. In the Frenkel defect, an. vacancy, in crystallography, absence of an atom or molecule from a point that it would normally occupy in a crystal. Such an imperfection (crystal defect) in the regular spacing of atoms ... WebSchottky defect occurs in those ionic crystals where the difference in size between cation and anion is small. Frenkel defect usually occurs in those ionic crystals where size of anion is quite large as compared to that of the cation. In Schottky defect, both cation and anion leave the solid crystal. In Frenkel defect, only the smaller ion ...
WebSchottky defects occur in ionic crystals where the size of anion is almost same with the size of the cation. One anion and one cation leave the crystal at the same time to create Schottky defect. None of them occupies the interstitial site again. One Schottky defect leads to the formation of two vacancies.
