In the case of insulators, a band gap and conduction band is respectively (a) very high empty. (b) very low, partially filled (c) very high, completely filled (d) very low, empty.

Answer: (a). Insulators: band gap very large ( > 3 eV). Electrons cannot cross it, so the conduction band is empty. So the answer is (a) very high, empty.

Energy Bands in Solids

In the case of insulators, a band gap and conduction band is respectively

Show answer and solution

Answer: (a)

Insulators: band gap very large ( $> 3\text{ eV}$ ).
Electrons cannot cross it, so the conduction band is empty.
So the answer is (a) very high, empty.
