Where, Eg = Energy band gap; K b = Boltzmann’s constants; Extrinsic Semiconductor. The conductivity of semiconductors can be greatly improved by introducing a small number of suitable replacement atoms called IMPURITIES. The process of adding impurity atoms to the pure semiconductor is called DOPING.
