    If the distance between the conduction band and valence band is 1 eV. This combination is

    A)  semiconductor                

    B)  conductor

    C)  metal                                  

    D)  insulator

    Correct Answer: A

    Solution :

                     Band gap (or energy gap) is the energy difference between the top of the valence band and the bottom of the conduction band. Insulators have higher band gap of usually greater than 3 eV, while semiconductors have a band gap of 1 eV.
