In an n- type silicon, which of the following statements is true ?
(a) Electrons are majority carries and trivalent atoms are the dopants.
(b) Electrons are majority carries and pentavalent atoms are the dopants.
(c ) Holes are minority carries and paentavalent atoms are the dopants.
(d) Holes are minority carries and trivalent atoms are the dopants.

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 Answer is:
C
In an n-type silicon the holes are the minority carriers. An n-type semiconductor is obtained when pentavalent atoms, such as phosphorus, are doped in silicon atoms.
