    n-type semiconductor is prepared by doping Si in a semiconductor by a :

    A)  pentavalent impurity

    B)  trivalent impurity

    C)  divalent impurity

    D)  monovalent impurity

    Correct Answer: A

    Solution :

    We know that n type semiconductor is negative type semiconductor it mean excess of electron is required. So, it can be formed by doping of pentavalent impurity in Si.
