Question

If the energy band gap ($E_g$) of a material is larger than 3 eV, the material is generally classified as:

Professor PC Thomas Classes · Answer

Materials with an energy band gap $E_g>3eV$ are typically insulators, as it is extremely difficult for thermal excitation at room temperature to promote electrons from the valence band to the conduction band.
