Question

In an n-type semiconductor, which of the following statements, is true?

• A. Holes are majority carriers and trivalent atoms are dopants
• B. Electrons are majority carriers and trivalent atoms are dopants
• C. Electron are minority carriers and pentavalent atoms are dopants
• D. Holes are minority carries and pentavalent atoms are dopants.

Answer 1

The correct option is D Holes are minority carries and pentavalent atoms are dopants.

The n-type semiconductor is formed by adding pentavalent impurity atoms to a pure semiconductor. In an n – type semiconductor, holes are minority carriers.
