Germanium and silicon behave as semiconductors because |
At room temperature, germanium and silicon behave as good conductors the energy gap between their conduction and valence bands is of the order of 1 eV the energy required to take out an electron from these atoms is very high their valence and conduction bands are overlapping |
the energy gap between their conduction and valence bands is of the order of 1 eV |
The correct answer is Option (2) → the energy gap between their conduction and valence bands is of the order of 1 eV Correct statement: ☀ the energy gap between their conduction and valence bands is of the order of 1 eV Explanation: Germanium and silicon act as semiconductors because they have a small energy band gap (≈1 eV), which allows some electrons to jump from the valence band to the conduction band at room temperature, enabling limited conductivity. |
