Solid State Question 269
Question: What type of crystal defect is indicated in the diagram below [AIEEE 2004] $ N{{a}^{+}}C{{l}^{-}}N{{a}^{+}}C{{l}^{-}}N{{a}^{+}}C{{l}^{-}} $ $ C{{l}^{-}} $ ยจ $ C{{l}^{-}} $ $ N{{a}^{+}} $ ยจ $ N{{a}^{+}} $ $ N{{a}^{+}} $ $ C{{l}^{-}} $ ยจ $ C{{l}^{-}} $ $ N{{a}^{+}} $ $ C{{l}^{-}} $ $ C{{l}^{-}} $ $ N{{a}^{+}} $ $ C{{l}^{-}} $ $ N{{a}^{+}} $ ยจ $ N{{a}^{+}} $
Options:
A) Interstitial defect
B) Schottky defect
C) Frenkel defect
D) Frenkel and Schottky defects
Show Answer
Answer:
Correct Answer: B
Solution:
In this diagram, equal number of cations $ (N{{a}^{+}}) $ and anions $ (C{{l}^{-}}) $ are missing, so it, shows schottky defect.
