Energy band definition class 12

Weba. Insulator. Insulator is that material in which current dose not flows easily e.g. Wood; paper, plastic, oil, mica etc The reason for insulation is the wide gape between the valance band and conduction band. A large amount of energy is required to shift electrons from the valence band in to the conduction band. Insulator Material Band. b. WebAs a result, the conduction band is empty. Only the electrons in a conduction band can move easily, so because there aren't any electrons in an insulator's conduction band, the …
