[AIIMS 1997; KCET (Engg.) 2002]
Options:
A) Donar
B) Acceptor
C) Intrinsic
D) Extrinsic
Show Answer
Answer:
Correct Answer: C
Solution:
$ \begin{matrix} \text{Intrinsic} \ \text{semiconductor} \ \end{matrix} $ Conductivity is due to the breaking of covalent bond $ \begin{matrix} \text{Extrisnsic} \ \text{semiconductor} \ \end{matrix} $ Conductivity is due to the breaking of covalent bond and excess of charge carriers due to impurity.
