Question

Which of the following is not true about doping of semiconductors?
Options
A Doping with group III element leads to p-type semiconductor.
B Doping with group V element leads to n-type semiconductor.
C Doping with group III elements leads to excess holes in valency band.
D Doping with group V elements leads to excess holes in the conduction band.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Group III elements (trivalent impurities) are 'acceptors' and lead to p-type semiconductors by creating excess holes in the valency band.Group V elements (pentavalent impurities) are 'donors' and lead to n-type semiconductors by providing excess electrons to the conduction band, not excess holes.

Hint

Consider the type of charge carriers produced by Group III vs. Group V doping.
