In energy band diagram of insulators, a band gap and the conduction band is respectively
Options:
Answer:
A
Solution:
In insulators, the energy gap between the valence band and the conduction band is very large (typically greater than ).
Due to this large band gap, electrons from the valence band cannot easily be excited to the conduction band even at room temperature.
Therefore, the valence band is completely filled and the conduction band remains empty.
Answer: very high, empty
