(a)
Interpretation:
Whether the given combination of elements would produce a semiconductor or not has to be explained
Concept Introduction:
Semiconductors are substances that conduct electricity either by addition of an impurity or by the effects of temperature on it. Semiconductors electrically conductivity lie between conductor and insulator. Semiconductors have small energy gap between valence band and conduction band.
The only elemental form of semiconductors is germanium, silicon and carbon (graphite form) whereas other semiconductors will have combination of elements whose valence electron count will total up to eight.

- 8.96 A business manager wants to provide a wider range of p- and n-type semiconductors as a strategy to enhance sales. You are the lead materials engineer assigned to communicate with this manager. How would you explain why there are more ways to build a p-type semiconductor from silicon than there are ways to build an n-type semiconductor from silicon?arrow_forwarda) Explain the band structure of an electrical conductor (metal), a semiconductor, and an insulator at 0 K by showing the valence and conduction bands and fermi energy levels. Explain how the electrical conduction takes place in these three types of materials. Give an example for each type of material. b)Explain what n and p-type semiconductors are using their band structures. Why?arrow_forwardDefine a semiconductor? Describe the two main types of semiconductorswhen it is doped with(a) group 13 element, (b) group 15 element.arrow_forward
