In a p-type semiconductor, which carriers are the majority carriers?
AThe hadrons
BThe holes
CThe halides
DThe helions
Answer & Solution
Correct answer: B. The holes
1. A trivalent dopant creates a vacancy in the bonding.
2. Those vacancies greatly outnumber the free electrons.
3. For such a material, the holes are the majority carriers and electrons are minority carriers.
4. So the answer is the holes.
