Schottky defect in a crystal arises due to

Options

  1. Acreation of equal number of cation and anion vacancies
  2. Bcreation of unequal number of cation and anion vacancies
  3. Cmigration of cations to interstitial voids
  4. Dmigration of anions to interstitial voids

Correct answer

A. creation of equal number of cation and anion vacancies

Step-by-step solution

In SCHOTTKY by defect equal number of cations and anions leave the crystal LATTICE to form equal number of cationic and anionic vacancies.
