Difference between Semiconductors and Insulators
| | Semiconductors | Insulators |
1. | In semiconductor effect of resistance is decrease and effect of temperature is amplify. | In insulator effect of resistance is decreases and cause of temperature is increases. |
2. | They require energy less than insulators and more than good conductors to eliminate an electron from the parent atom. | They require extremely large electric field to remove them from the attraction of nucleus. |
3. | The conductivity of semiconductor is sensible. | The conductivity of insulator is very low. |
4. | These are the materials whose valence electrons are bound rather loosely to their atom. | There are materials in which valence electrons use are bound extremely highly to their parent atom. |
5. | It has sensible resistivity. | It has extremely high resistivity. |
6. | It has small forbidden gap. | It has large forbidden gap. |
