Consider the band diagram shown below. Which type of conductor is represented by this type of band diagram? The material is a metallic conductor. The material is an insulator (Eg > 2 eV).. The material is a semiconductor (0

Solution

Energy bands consisting of a large number of closely spaced energy levels exist in crystalline materials. The bands can be thought of as the collection of the individual energy levels of electrons surrounding each atom.

In semiconductors there is an gap between the valence and conduction bands. This energy gap reflects the amount of energy that would be needed to remove an electron from it\'s parent atom (ie to transfer it from the valence to the conduction band).

Energy gap here is big so it is an insulator.
