(d) The n-type semiconductors are obtained when Si or Ge are doped with elements of group 15, eg, arsenic (As), while p-type semiconductors are obtained when Si or Ge are doped witlh traces of elements of group 13, ie, indium (In), boron (B).
Note : The conductivity of semiconductors increases with rise in temperature
