    In a semiconductor separation between conduction and valence band is of the order of :

    A)  0 eV            

    B)  1 eV

    C)  10 eV           

    D)  50 eV

    Correct Answer: B

    Solution :

     In conductance, separation between conduction and valence bands is zero and in insulated, it is greater than 1 eV. Hence, in semiconductors the separation between conduction and valence bond is 1eV.
