Question

Write down the majority and minority charge carriers in n-type of semiconductor.

Hint:

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

Answer 1

Step 1: N-type Semiconductor.
In an n-type semiconductor, the material is doped with a group V element (such as phosphorus), which has five valence electrons. These extra electrons are free to move and contribute to electrical conduction.

Step 2: Majority Charge Carriers.
The majority charge carriers in an n-type semiconductor are electrons. These are the free electrons provided by the donor atoms.

Step 3: Minority Charge Carriers.
The minority charge carriers in an n-type semiconductor are holes. These are the absence of electrons in the valence band, which behave like positive charge carriers.

Step 4: Conclusion.
Thus, in an n-type semiconductor, the majority charge carriers are electrons, and the minority charge carriers are holes.
