Question

Energy gap between conduction band and valence band in case of semiconductor is​

Answer 1

Answer:

5.5 eV

Explanation:

Energy gap between conduction band and valence band in case of semiconductor is​ 5.5 eV

a is the atomic spacing in an actual crystal of diamond. At that spacing the orbitals form two bands, called the valence and conduction bands, with a 5.5 eV band gap between them. Very few electrons have the energy to surmount this wide energy gap and become conduction electrons, so diamond is an insulator.
