Write difference between schottky and Frenkel defect
Answers
Answer:
difference between schotty amd frenkel :-
Explanation:
Schottky defect occurs when oppositely charged atoms (cation and anion) leave their corresponding lattice sites and create a pair of Vacancy Defects. Since both cation and anion leave the lattice sites at the same time, so overall electrical neutrality of the crystal is maintained; however, density reduces because of the vacancies. Schottky defects occur in ionic crystals where the size of anion is almost same with the size of the cation. Read more about Schottky defect.
Schottky Defect - Point Defect - Defects in Ionic Solid
Frenkel Defect is one type of point defect where an atom (better to say ion, especially cation) leaves its original lattice site and occupies an interstitial position on the same crystal. Usually, this type of defect is observed in ionic solids, where size of anion is substantially larger than the size of cation
