High speed tunnel diodes
WebFeb 24, 2012 · 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 ... WebTunnel diode is a highly doped semiconductor device and is used mainly for low-voltage high-frequency switching applications. It works on the principle of Tunneling effect. It is also called as Esaki diode named after Leo Esaki, who in 1973 received the Nobel Prize in Physics for discovering the electron tunneling effect used in these diodes.
