Types of Tunnel Diode
There are different types of tunnel diode based on their structure and material used in their development.
1. Single-Well Tunnel Diode: This type of diode exhibits negative differential resistance and is used in amplifiers and oscillator circuits.
2. Double-Barrier Tunnel Diode: This diode is used in applications such as millimeter wave oscillators because it operate at higher frequencies.
3. Superlattice Tunnel Diode: This is used for more precise control over the tunneling process and can lead to improved performance characteristics.
4. Resonant Tunnel Diode
5. Esaki Inter-band Tunnel Diode: Esaki inter-band tunnel diode is an extension of the traditional tunnel diode is used for higher-frequency applications.
Tunnel Diode
The tunnel diode is also known as the “Esaki Diode”. It was invented by “Leo Esaki” in 1957, and for this invention, received the he received Nobel in 1973. It exhibits negative resistance, negative resistance means current decreases when voltage increases.
