This potential difference can alter the flow of majority carriers so that the pn junction can be used as an opportunity for the diffusion of electrons and holes.

Working of a pn junction diode. A pn junction is the simplest form of the semiconductor diode. A p n junction diode is formed by doping one side of a piece of silicon with a p type dopant boran and the other side with a n type dopant phosphorusge can be used instead of silicon. This is the basic construction of the p n junction diode.

These materials are n type having electrons are majority carrier and p type material having holes are majority carrier. With proper biasing pn diode allows current to flow in single direction. Its made up from a small piece of semiconductor material usually silicon it allows the electric current to flow in one direction while opposes the current in other direction.

The n side will have large number of electrons and very few holes due to thermal excitation whereas the p side will have high concentration of holes and very few electrons. A pn junction diode is a two terminal semiconductor device. Doping with acceptor creates p type semiconductor while doping with donors produces n type.

Thus a pn junction is formed in diode. Pn junction diode is a device made of two semiconductor material joined together with the required amount of impurity. The p n junction diode is a two terminal device.

Due to this a process called diffusion takes place. A pn junction diode is one of the simplest semiconductor devices around and which has the characteristic of passing current in only one direction only. The pn junction diode is the basic semiconductor diode format.

Working of pn junction diode if an external potential is applied to the terminals of pn junction it will alter the potential between the p and n regions. 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. A pn junction diode is a two terminal single crystal semiconductor device whose one side is doped with acceptors and other side by donors.

However unlike a resistor a diode does not behave linearly with respect to the applied voltage as the diode has an exponential current voltage.
