Question

What are majority and minority charge carriers of p-type and n-type semiconductors?

Hint:

In semiconductors, majority carriers dominate conduction. Drift current is due to electric field; diffusion current arises from concentration differences.

Answer 1

Majority and Minority Charge Carriers:
- In a p-type semiconductor:
$\bullet$ Majority carriers: Holes

$\bullet$ Minority carriers: Electrons
- In an n-type semiconductor:
$\bullet$ Majority carriers: Electrons

$\bullet$ Minority carriers: Holes
