State the value of the energy band gap difference between the valence band $(E_V)$ and the conduction band $(E_C)$ for $C$ (Diamond), $Si$, and $Ge$.
(N/A) The energy band gap $(E_g = E_C - E_V)$ represents the energy difference between the conduction band and the valence band.
For $C$ (Diamond), the energy band gap is approximately $5.4 \text{ eV}$.
For $Si$ (Silicon), the energy band gap is approximately $1.1 \text{ eV}$.
For $Ge$ (Germanium), the energy band gap is approximately $0.7 \text{ eV}$.
For $C$ (Diamond), the energy band gap is approximately $5.4 \text{ eV}$.
For $Si$ (Silicon), the energy band gap is approximately $1.1 \text{ eV}$.
For $Ge$ (Germanium), the energy band gap is approximately $0.7 \text{ eV}$.
