    When   the   conductivity   of   a semiconductor is only due to breaking of covalent bonds, the semiconductor is called:

    A)  intrinsic                                

    B)  extrinsic

    C)  p-type                                

    D)  n-type

    Correct Answer: A

    Solution :

    When conductivity of semiconductor is only due to breaking of covalent bond, then semiconductor is intrinsic (pure) because here due to thermal agitation, some covalent bonds are broken and some electrons are free to conduct current.
