Question

    Doping silicon with gallium forms what type of semiconductor?

    A N-type semiconductor Correct Answer Incorrect Answer
    B Superconductor Correct Answer Incorrect Answer
    C P-type semiconductor Correct Answer Incorrect Answer
    D Insulator Correct Answer Incorrect Answer

    Solution

    When silicon is doped with gallium, the resulting material becomes a p-type semiconductor. Gallium introduces "holes" in the crystal lattice that can accept electrons, facilitating electrical conductivity.
