Difference between Semiconductors and Conductors

Difference between Semiconductors and Conductors Points : Difference between Semiconductors and Conductors, comparision between Semiconductors and Conductors, Semiconductors vs Conductors
Difference between Semiconductors and Conductors
Semiconductors
Conductors
1.Equally resistivity and contract effects are extremely sensitive to tiny change in physical conditions.Both resistivity and contact effects are extremely sensitive to tiny changes in physical conditions.
2.Moving carrier of electric current are originated due to inclusion of thermal radiant or electric energy as of an external source.Current carriers here are free electrons which exist whether outside energy is functional on not.
3.Their resistivity is frequently high and temperature coefficient of resistance is constantly negative.The resistivity is extremely low and the temperature coefficient of resistant is not stable.
4.Semiconductor has negative temperature coefficient of resistance.Conductor has positive temperature coefficient of resistance.
5.There is moderate number of electrons accessible for conduction.There is large number of electrons accessible for conduction.
6.These are materials have filled energy bands with small forbidden zones.These are materials by unfilled or overlap energy bands.
7.At low temperature, they become dielectric.At extremely low temperatures i.e. absolute zero temperature they become superconductors.
