In a semiconductor, the concentration of electrons is \[8\times {{10}^{14}}/c{{m}^{3}}\] and that of the holes is \[5\times {{10}^{12}}c{{m}^{3}}.\] The semiconductor is
A) p-type
B) n-type
C) Intrinsic
D) pnp type
Correct Answer:
B
Solution :
[b] Since \[{{n}_{e}}>{{n}_{h}},\]the semiconductor is N-type
