Question

Write five differences between p-type and n-type semiconductor.

Answer 1

Difference between n-type and p-type semiconductors:

n-type semiconductor	p-type semiconductor
1. Electrons are majority charge carriers and holes are minority charge carriers.	1. Holes are majority charge carriers and electrons are minority charge carriers.
2. The majority of charge carriers move from low potential to high potential.	2. The majority of charge carriers move from high potential to low potential.
3. An donor is a doping atom that can produce an n-type semiconductor whenever introduced to a semiconductor.	3. An acceptor is a contaminating atom that could produce a p-type semiconductor whenever introduced to a semiconductor.
4. Pentavalent impurities are added.	4. Trivalent impurities are added.
5. It has donor energy levels that are very close to the conduction band.	5. It has acceptor energy levels that are very close to the valence band.
