Question

Explain, insulator, semiconductor and conductor in terms of band gap

Answer 1

Even in semiconductors, there is a band gap, but compared to insulators it is so small that even at room temperature electrons from the valence band can be lifted into the conduction band. The electrons can move freely and act as charge carriers. ... A pure undopedsemiconductor is known as intrinsicsemiconductor.

Answer 2

Conductors
Conductor are those substance in which electricity can pass through it.
Example : Copper, Silver

Insulators
Insulators are those substance in which electricity cannot pass through it.
Example : Plastic, Paper

Semiconductor
Semiconductor are those solid substance which allows heat and electricity to pass through it in particular condition
