Question

Which of the following statements is NOT true about doping of semiconductors?
Options
A Doping with group III elements leads to p-type semiconductor.
B Doping with group V elements leads to n-type semiconductor.
C Doping with group III elements leads to excess holes in the 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

Doping with group V elements (pentavalent impurities) leads to n-type semiconductors, where the extra valence electron from the impurity becomes a free electron in the conduction band, leading to an excess of electrons, not holes, in the conduction band. Options A, B, and C are true statements about doping.

Hint

Recall the definitions of n-type and p-type semiconductors and how they are formed by doping.
