Unformatted text preview: est? Is there a noticeable pattern in the band gap energy of III-V compounds related to the column III element? (b) Among the indirect materials listed in Appendix III, which one has the smallest bandgap energy, 2. Based on Fig. 3.3, explainroom temperature? Which one has the largest bandgap energy, and and what is that at why the bandgap energy of a diamond crystal would increase (or decrease) with respect to that at room temperature when it is cooled to liquid nitrogen temperature. what is that? 3. The for InSb is pictured below. 4. The bonding modelbonding model for InSb is pictured below. (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. EE 332 Spring 2014 (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....
