Question

Which are the majority carriers and minority carriers in an n-type semiconductor?

Options

• Electrons are majority carriers; holes are minority carriers.

• Donor ions are majority carriers; electrons are minority carriers.

• Electrons and holes are both majority carriers.

• Holes are majority carriers; electrons are minority carriers.

Answer 1

Free electrons greatly outnumber holes in an n-type semiconductor. Electrons are therefore the majority carriers, and holes are the minority carriers.
