For a p-type semiconductor which of the following statements is true?
A Electrons are the majority carriers and trivalent atoms are the dopants.
B Holes are the majority carriers and trivalent atoms are the dopants.
C Holes are the majority carriers and pentavalent atoms are the dopants.
D Electrons are the majority carriers and pentavalent atoms are the dopants.

Detailed Solution

In a p-type semiconductor, an intrinsic semiconductor is doped with trivalent impurities. These create deficiencies of valence electrons called holes, which are the majority charge carriers. So holes are the majority carriers and trivalent atoms are the dopants.
