In a n-type semiconductor, which of the ...

In a `n`-type semiconductor, which of the following statement is true?

A

Electrons are majority carriers and trivalent atoms are the dopants.

B

Electrons are minority carriers and pentavalent atoms are the dopants.

C

Holes are minority carriers and pentavalent atoms are the dopants.

D

Holes are majority carriers and trivalent atoms are the dopants.

Text Solution

Verified by Experts

The correct statement is (c).
In an-type silicon, the electrons are the majority carriers, while the holes are the minority carriers. An n-type semiconductor is obtained when pentavalent atoms, such as phosphorus, are doped in silicon atoms.
