Vedclass · Answer

(D) The energy gap $(E_g)$ is the energy difference between the valence band and the conduction band.- For metals,the valence and conduction bands overlap,so $E_g = 0$.- For semiconductors,the energy gap is small,typically $E_g - For insulators (often referred to as non-metals in this context),the energy gap is very large,typically $E_g > 3 \ eV$.Therefore,the correct answer is insulators or non-metals.

Which of the following substances has an energy gap $(E_g)$ greater than $3 \ eV$?
