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 |
