    The intrinsic semiconductor becomes an insulator at [EAMCET (Med.) 1995; KCET (Engg./Med.) 1999;  MP PET 2000; CBSE PMT 2001]

    A)            \[0{}^\circ C\]                      

    B)            \[-100{}^\circ C\]

    C)            \[300\ K\]                              

    D)            \[0\ K\]

    Correct Answer: D

    Solution :

               At 0K temperature semiconductor behaves as an insulator, because at very low temperature electrons cannot jump from the valence band to conduction band.
