5. CHAPTER:14 SOLID AND SEMICONDUCTOR DEVICES
Q. 1. What are energy bands? Write any two distinguishing features
between conductors, semiconductors and insulators on the basis of
energy band diagrams. [CBSE (AI) 2014,
North 2016]
OR
Draw the necessary energy band diagrams to distinguish between
conductors, semiconductors and insulators. How does the change in
temperature affect the behavior of these materials? Explain briefly.

6. (a) In conductors: Valence band and conduction band overlap each other.
In semiconductors: Valence band and conduction band are separated by a small energy gap.
In insulators: They are separated by a large energy gap.
(b) In conductors: Large number of free electrons are available in conduction band.
In semiconductors: A very small number of electrons are available for electrical conduction.
In insulators: Conduction band is almost empty i.e., no electron is available for conduction

17. CHAPTER 12 : ATOMS
