A semiconductor is doped with a donor impurity

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.

P-type semiconductor is formed when (A). As impurity is mxied in Si (B). Al impurity is mixed in Si (C). B impurity is mixed in Ge (D). P impurity is mixed in Ge.
