Question

forbidden energy gap in a conductor is​

Answer 1

$\huge\mathfrak\purple {☆ᴀɴSᴡᴇʀ☆}$

The forbidden gap energy is of the order of 0.7eV for Ge and 1.1eV for Si. There are no electrons in the conduction band. The valence band is completely filled at 0 K. With a small amount of energy that is supplied, the electrons can easily jump from the valence band to the conduction band.Mar 14, 2016
