A) Frenkel defect
B) Schottky defect
C) Metal excess defect
D) Metal deficiency defect
Correct Answer: C
Solution :
[c] \[ZnO\xrightarrow{\Delta }Z{{n}^{2+}}+\frac{1}{2}{{O}_{2}}+2{{e}^{-}}\] |
The remaining \[Z{{n}^{2+}}\] ions occupy the interstitial voids of remaining crystal, thus causing metal excess defect. |
