Vedclass · Answer

(C) The forbidden energy gap $(E_g)$ of a semiconductor depends on temperature. For Germanium $(Ge)$, the forbidden energy gap at $0 \,K$ is approximately $0.74 \,eV$. As the temperature increases, the energy gap decreases slightly. At room temperature $(300 \,K)$, the value is approximately $0.67 \,eV$ to $0.72 \,eV$. Comparing the given options, $0.74 \,eV$ is the standard value for $Ge$ at $0 \,K$.

The forbidden energy gap for $Ge$ crystal at $0 \,K$ is (in $\,eV$)
