Question

What are majority and minority charge carriers in an extrinsic semiconductor?

Hint:

In an extrinsic semiconductor, the type of doping determines the majority and minority charge carriers.

Answer 1

In an extrinsic semiconductor, the majority and minority charge carriers are determined by the type of doping. - Majority charge carriers: In an n-type semiconductor (doped with donor atoms), the majority charge carriers are electrons, which are the free negatively charged particles. In a p-type semiconductor (doped with acceptor atoms), the majority charge carriers are holes, which are the absence of electrons and can be treated as positive charge carriers. - Minority charge carriers: In an n-type semiconductor, the minority charge carriers are holes, and in a p-type semiconductor, the minority charge carriers are electrons.
