For a p-type semiconductor, which of the following statements is true?

A

electrons are the majority carriers and pentavalent atoms are the dopants

B

electrons are the majority carriers and trivalen atoms are the dopants

C

holes are the majority carriers and trivalen atoms are the dopants

D

holes are the majority carriers and pendtavlent atoms are the dopants

Text Solution

Verified by Experts

In p-type semiconductor extra holes are created by doping of trivalent hence option (c ) is correct.
