☑ How Does Pn Junction Diode Work

To understand how a pn junction diode works begin by imagining two separate bits of semiconductor one n type the other p type. When semiconductors of different types are put next to each other interesting things happen.

The junction of n and p semiconductors is free of charge carriers.

How does pn junction diode work. As a result the free electrons and holes near the junction tend to eat each other producing a region depleted of any moving charges. Understanding a forward biased pn junction not only helps in understanding how a diode works but practically any semiconductor devices transistors thyristor triac photocouplers etc. All the themes in the soundtrack.

Well discuss forward bias its effect on the depletion region and the effect barrier potential has during forward bias. Pn junction diode is a two terminal device the characteristics of diode depends on the polarity of the external potential applied to the pn junction diode. Hence the region is called as depletion region.

In the most basic junction the pn junction a diode is formed. N type and p type material are of little use by themselves. It is used for many forms of rectification for current levels both large and small as well as high and low voltage levels and it finds many uses in all manner of electronic circuits.

Rather a single piece of silicon would have each half doped accordingly. This creates what is called the depletion zone.

Developed under teaching innovation project 11 293 of universidad de granada spain creative commons by noncommercial nonderivs. The pn junction diode is the basic semiconductor diode format. Bring them together and join them to make one piece of semiconductor which is doped differently either side of the junction.

Its important to note that the manufacturer does not create separate p type and n type material and then glue them together. To understand how a pn junction diode works begin by imagining two separate bits of semiconductor one n type the other p type. Together they form a p n junction.

Well cover the diode definition further and lay the foundation of why a diode acts like it does when an n doped material and a p doped material are put together.
