In tunnel diode electric current is caused by tunneling. In reverse biased condition also tunnel diode is an excellent conductor due to its high doping concentrations. Enhanced Radiation Hardness In Soi Mosfet With Embedded The Fabrication Process Of The Proposed Structure After What Is A Tunnel Diode Quora That is why a tunnel diode is extensively used in special applications requiring very fast switching speeds like high speed computer memories and high frequency oscillators etc. Tunnel diode structure . Pulsed bond tunnel diode structure. Planar tunnel diode structure. This is a relatively straightforward tunnel diode structure. It is also used in high frequency oscillators and amplifiers. Tunnel diodes are made from germanium or gallium arsenide due to their highest peak voltage to valley point swing. Esaki diodes was named after leo esaki...
