Question

(iii) With the help of suitable diagrams, on the basis of band theory, explain the difference

between a conductor, a semiconductor & an insulator.​

Answer 1

Explanation:

In a semiconductor, the gap between the valence band and conduction band is smaller. ... The difference between insulators and semiconductors is due to a small amount of impurity added to a semiconductor which affects the energy bands. This process is called doping.
