Question

In an n-type silicon, which of the following statement is true:

Options

• Electrons are majority carriers and trivalent atoms are the dopants.

• Electrons are minority carriers and pentavalent atoms are the dopants.

• Holes are minority carriers and pentavalent atoms are the dopants.

• Holes are majority carriers and trivalent atoms are the dopants.

Answer 1

Holes are minority carriers and pentavalent atoms are the dopants.

Explanation:

In an n-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.
