How much will be the energy gap between filled band and empty band in insulators? |
They are overlapping. Very small gap between filled band and empty band. Very large energy gap between filled band and empty band. None of the above. |
Very large energy gap between filled band and empty band. |
The energy gap between filled band and empty band is very large in insulators. The electrons cannot freely move in insulators because of this forbidden gap. Thus, they cannot conduct electricity. |
