Vedclass · Answer

(A) In semiconductors,the valence band and conduction band are separated by a small energy gap,known as the forbidden energy gap $(E_g)$.For semiconductors like Silicon $(Si)$ and Germanium $(Ge)$,this energy gap is typically around $1 \ eV$.Specifically,for $Si$,$E_g \approx 1.1 \ eV$ and for $Ge$,$E_g \approx 0.7 \ eV$.Therefore,the order of the energy gap in semiconductors is $1 \ eV$.

The energy gap in semiconductors is of the order of ........ $eV$.
