Question

Carbon, silicon and germanium have four valence electrons each. These are characterised by valence and conduction bands separated by energy band gap respectively equal to $\left(E_g\right)_{\mathrm{C}},\left(E_g\right)_{\mathrm{Si}}$ and $\left(E_g\right)_{\mathrm{Ge}}$. Which of the following statements is true?
