Difference between Conductors and semi conductor
Difference between Conductors and semi conductor are in tabular form below –
Conductor |
Semi-Conductor |
1) A substance that conduct electricity is called conductor. | A substance conduct electricity but in moderate is but in moderate is called semi-conductor. |
2) The conductivity of the conductor is high. | Conductivity of the conductor is moderate. |
3) The conductor has a large number of electron for transmission. | The semiconductor has very little number of electron for transmission. |
4) The temperature coefficient of a conductor is positive | the temperature coeficient of a semiconductor is negative. |
5) The conductor doesn’t have Forbidden gap. | the semiconductor has a forbidden gap. |
6) The resistancy value of the conductor is less than 10-5 Ohm so it is negligible. | the resistancy value of the semiconductor is 10-5 Ohm m to 5 Ohm m |
7) The amount of current carriers at usual temprature in the conductor is very high. | the amount of current carries at usual temperature in the semi conductor is low. |
8) The conductivity value of the conductor is very high 10-7 Mho/m. | the conductivity value of the semiconductor is among those of insulator and conductor. |
9) The flow of current in a conductor is due to free electron. | the flow of electron in semiconductor due to holes as well as free electron. |
10) The valence shell electron in a conductor are one in the outermost shell. | valence shell electron in a semiconductor are four in a outermost shell. |
11) The formation of the conductor can be done by metallic bonding. | the formation of the semiconductor it can be formed by covalent binding. |
12) The O-kelvin behaviour of conductor acts as a superconductor. | the formation of the semiconductor acts like an insulators. |
13) The band overlap in a conductor is both the valence band and conduction band. | semiconductor Has both bands which are divided with an energy space of 1.1 eV. |
14) Examples of Conductors:- Copper, Silver, Mercury and Aluminium. | Examples of semiconductors:- Silicon, Germanium. |
