A) \[{{n}_{e}}>{{n}_{h}}\]
B) \[{{n}_{h}}>{{n}_{e}}\]
C) \[{{n}_{e}}={{n}_{h}}\]
D) \[{{n}_{e}}={{n}_{h}}=0\]
Correct Answer: C
Solution :
Pure semiconductors are intrinsic semiconductors. They have not any impurity. Hence, number of electrons in the conduction band is equal to the number of holes in valence band. It means\[{{n}_{e}}={{n}_{h}}\].
