Write the definition of valence band and conduction band.
(N/A) $1$. Valence Band: The energy band which includes the energy levels of the valence electrons is known as the valence band. It is the highest energy band that is completely or partially filled with electrons at $0 \ K$.
$2$. Conduction Band: The energy band above the valence band,which is either empty or partially filled with electrons,is known as the conduction band. Electrons in this band are responsible for the electrical conduction in a material.
$2$. Conduction Band: The energy band above the valence band,which is either empty or partially filled with electrons,is known as the conduction band. Electrons in this band are responsible for the electrical conduction in a material.
