Draw the "energy bands" diagram for a (i) pure semiconductor (ii) insulator. How does the energy band, foe a pure semiconductor, get affected when this semiconductor is doped with an acceptor impurity donor impurity? Hence discuss why the 'holes' and the 'electrons' respectively, become the 'majority charge carriers' in these two cases.
