Bring them together and join them to make one piece of semiconductor which is doped differently either side of the junction. Hence the region is called as depletion region.

This creates what is called the depletion zone.
Pn junction diode works. A pn junction diode is a two terminal single crystal semiconductor device whose one side is doped with acceptors and other side by donors. Thus a pn junction is formed in diode. A pn junction is the simplest form of the semiconductor diode.
Developed under teaching innovation project 11 293 of universidad de granada spain creative commons by noncommercial nonderivs. The formation of pn junction in a single crystal. All the themes in the soundtrack.
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. Doping with acceptor creates p type semiconductor while doping with donors produces n type. In this tutorial we are going to talk about this pn junction as it forms the basic definition of a diode.
As a result the free electrons and holes near the junction tend to eat each other producing a region depleted of any moving charges. The pn junction after doping an intrinsic semiconductor material usually silicon so that part of it is p type and the other part is n type a pn junction is formed at the boundary between the p and n regions. The junction of n and p semiconductors is free of charge carriers.
In ideal conditions this pn junction behaves as a short circuit when it is forward biased and as an open circuit when it is in the reverse biased. To understand how a pn junction diode works begin by imagining two separate bits of semiconductor one n type the other p type. To understand how a pn junction diode works begin by imagining two separate bits of semiconductor one n type the other p type.
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. The pn junction diode is the basic semiconductor diode format.
