Question

The minority charge carriers in n type of semiconductors:

• A. electrons
• B. holes
• C. both electrons and holes
• D. none of them

Hint:

In n-type semiconductors, electrons are the majority charge carriers, and holes are the minority charge carriers.

Answer 1

The Correct Option is B

In an n-type semiconductor, the majority charge carriers are electrons, while the minority charge carriers are holes.
This is because n-type semiconductors are doped with donor atoms, which release extra electrons into the conduction band, making these electrons the majority charge carriers. The term "holes" refers to the absence of electrons in the lattice, and they behave like positive charge carriers in the semiconductor.
The minority carriers are those which are less abundant in the material. In an n-type semiconductor, holes are the minority charge carriers because the material has more free electrons than holes.
Hence, the correct answer is option (B) holes.
