Answer:
The intrinsic semiconductor (Si or Ge) has charge carriers (holes and electrons) produced due to thermal agitation. But their number is very low at room temperature and has a very low conductivity. To increase the charge carriers i.e. electrons or holes, the dopants (or impurities) such as pentavalent or trivalent impurities are added to increase the conductivity of the intrinsic semiconductor.
