WebTunnel Diode. Tunnel diode was invented by Leo Esaki in 1958 for which he received Nobel prize in 1973, which is why it is also known as Esaki diode. A tunnel diode is a heavily doped P-N junction diode. It works on the principle of the tunneling effect. Due to heavy doping concentration, the junction barrier becomes very thin. WebGenerally, materials like GaAs, Si, Ge or InP are used for its construction. However, GaAs is preferred because of its low noise behaviour. Basically, it uses a slightly different structure from a normal diode. Because we know that a normal PN junction diode breaks down under avalanche condition.
