Energy bands consisting of a large number of closely spaced energy levels exist in crystalline materials. Each band is formed due to the splitting of one or more atomic energy levels.
Conductors- Electric current and heat can flow freely
Insulators- It does not allow electric current and heat to flow.
Semi Conductors- Conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects.
Hope this helps you
