Semiconducting Devices Question 135
Question: The forbidden energy band gap in conductors, semiconductors and insulators are $ EG _{1},EG _{2} $ and $ EG _{3} $ respectively. The relation among them is
[MP PMT 1994; RPMT 1997]
Options:
A) $ EG _{1}=EG _{2}=EG _{3} $
B) $ EG _{1}<EG _{2}<EG _{3} $
C) $ EG _{1}>EG _{2}>EG _{3} $
D) $ EG _{1}<EG _{2}>EG _{3} $
Show Answer
Answer:
Correct Answer: B
Solution:
In insulators, the forbidden energy gap is very large, in case of semiconductor it is moderate and in conductors the energy gap is zero.
