4. Doping: The bonding model for InSb is pictured below. S--S Sb (a) Draw the bonding model for InSb depicting the removal of the colored In and Sb atoms (b) Redraw the bonding model for InSb showing the insertion of Si atoms into the missing In and Sb atom sites (c) Is the InSb doped p- or n-type when Si atoms replace In atoms? Explain (d) Is the InSb doped p- or n-type when Si atoms replace Sb atoms? Explain (e) Draw the energy band diagram for InSb when InSb is doped with Si on (i) In sites and (ii) on Sb sites
