Conductors are such materials in which the forbidden energy gap disappears as the valence band and conduction band become very close that they overlap. Examples: Copper, Aluminum. The following figure shows the structure of energy bands in conductors.
Characteristics
The following are the characteristics of Conductors.
· There exists no forbidden gap in a conductor.
· The valance band and the conduction band gets overlapped.
· The free electrons available for conduction are plenty.
· A slight increase in voltage, increases the conduction.
· There is no concept of hole formation, as a continuous flow of electrons contribute the current.
