    The energy gap between the valence band and the conduction band for a material is\[6\text{ }eV\]. The material is:

    A)  an insulator

    B)  a metal

    C)  an intrinsic semiconductor

    D)  a superconductor

    E)  a doped semiconductor

    Correct Answer: A

    Solution :

    Insulators have large energy gap between valence and conduction band (about 6 eV), while semiconductors have a smaller one and conductors, the smallest energy gap.
