Vedclass · Answer

(A) The forbidden energy gap $(E_g)$ represents the minimum energy required for an electron to jump from the valence band to the conduction band.For Germanium $(Ge)$ at room temperature $(300 \ K)$,the forbidden energy gap is approximately $0.72 \ eV$.For Silicon $(Si)$ at room temperature $(300 \ K)$,the forbidden energy gap is approximately $1.1 \ eV$.Therefore,the correct value for Germanium is $0.72 \ eV$.

The energy required for an electron to jump the forbidden band for germanium at room temperature is $........... eV$.
