A basic equivalent circuit of a tunnel diode consists of ;
series inductance Ls,
the series resistance Rs,
the diode capacitance Cj
the negative resistance = R.
Additional Information
- A tunnel diode (also known as a Esaki diode) is a type of semiconductor diode that has effectively “negative resistance” due to the quantum mechanical effect called tunneling.
- Tunnel diodes have a heavily doped pn junction that is about 10 nm wide.
- The heavy doping results in a broken band gap, where conduction band electron states on the N-side are more or less aligned with valence band hole states on the P-side.
