Question

In Schottky defect

• A. An ion moves to interstial position between the lattice points
• B. Electrons are trapped in a lattice site
• C. Crystal remains electrically neutral
• D. Some extra cations are present in interstitial space

Answer 1

The correct option is C Crystal remains electrically neutral

In Schottky defect equal number of anions and cations are missing from their normal lattice sites. So equal number of cationic and anionic holes will be developed. Hence the crystal maintains electrical neutrality.
