Tunnel diode is used as amplifier and oscillator .
given figure is tunnel diode circuit.
The tunnel diode exhibits special feature known as negative resistance. This feature makes it useful to develop microwave amplifier and oscillator. Tunnel is normally constructed using germanium or gallium arsenide. Here p region and n regions are much more heavily dopped in comparison to conventional diode used as rectifier.
hope it helps
