A tunnel diode—also called Esaki diode because Leo Esaki invented it in 1957—is a heavily doped PN junction diode that exhibits negative resistance and high conductivity due to the tunneling effect. In signal diodes (small signal diodes and rectifier diodes), charge carriers gradually overcome the depletion region. In a tunnel diode, the charge carriers spontaneously…
What are the different types of diodes?
A diode is the most basic semiconductor device. Yet, it has endless applications. In semiconductor electronics, the p-n junction as a basic diode serves as the foundation for all other sophisticated semiconductor components and their design. The design principles that apply to a semiconductor diode are the same applies to transistors and other components. Interestingly,…
