Question:

$E_g$ (energy band-gap) for silicon is greater than that for germanium. Therefore, it can be concluded that

Options:

a greater number of electron hole pairs will be generated in silicon than in germanium at room temperature

less number of electron hole pairs will be generated in silicon than in germanium at room temperature

an equal number of electron hole pairs will be generated in both at lower temperatures

an equal number of electron hole pairs will be generated in both at higher temperatures
