    In which of the following statements, the obtained impure semiconductor is of\[p-type\]?

    A)  Germanium is doped with bismuth

    B)  Silicon is doped with antimony

    C)  Germanium is doped with gallium

    D)  Silicon is doped with phosphorus

    Correct Answer: C

    Solution :

    : p-type semiconductor is obtained when silicon (Si) or germanium (Ge) is doped with trivalent impurity like, boron, aluminium (Al), gallium (Ga) etc. n-type semiconductor is obtained when silicon (Si) or germanium (Ge) is doped with pentavalent impurity like arsenic (As), antimony (Sb), bismuth(Bi) etc.
