Answer:
hi frnd...
A Tunnel diode is a heavily doped p-n junction diode in which the electric current decreases as the voltage increases.
In tunnel diode, electric current is caused by “Tunneling”. The tunnel diode is used as a very fast switching device in computers. It is also used in high-frequency oscillators and amplifiers.
hope it helps.....

Explanation:
A Tunnel Diode is a heavily doped p-n junction diode. The tunnel diode shows negative resistance. When voltage value increases, current flow decreases. Tunnel diode works based on Tunnel Effect.

Leo Esaki invented Tunnel diode in August 1957. Therefore, it is also called as Esaki diode. The materials used for this diode are Germanium, Gallium arsenide and other silicon materials. Tunnel diode shows a negative resistance in their operating range. So, it can be used as amplifier, oscillators and in any switching circuits.
