Vedclass · Answer

(C) The energy band gap $(E_g)$ is the energy difference between the valence band and the conduction band.In metals,the valence and conduction bands overlap,so $E_g = 0$.In semiconductors,the energy band gap is small,typically around $1 \ eV$.In insulators,the energy band gap is very large,typically $E_g > 3 \ eV$,which prevents electrons from jumping from the valence band to the conduction band even at room temperature.Therefore,insulators have the maximum energy band gap.

In which material is the energy band gap maximum?
