Question

    In an n-type silicon, which of the following statements

    is true:
    A Electrons are majority carriers and trivalent atoms are the dopants. Correct Answer Incorrect Answer
    B Electrons are minority carriers and pentavalent atoms are the dopants. Correct Answer Incorrect Answer
    C Holes are majority carriers and trivalent atoms are the dopants. Correct Answer Incorrect Answer
    D Holes are minority carriers and pentavalent atoms are the dopants. Correct Answer Incorrect Answer

    Solution

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