☑ Pn Junction Diode Pdf In Hindi

A pn junction is formed when an n type material is fused together with a p type material creating a semiconductor diode in the previous tutorial we saw how to make an n type semiconductor material by doping a silicon atom with small amounts of antimony and also how to make a p type semiconductor material by doping another silicon atom with boron. The junction of n and p semiconductors is free of charge carriers.

Hello friends this is my new video in this video i will explaining you in very simple language what is p n junction diode in hindi 2017.

Pn junction diode pdf in hindi. P n junctions consist of two semiconductor regions of opposite type. What is a pn junction. The contact surface between the layers of p type and n type semiconductor pieces plated together so as to form a p n junction is called the p n junction.

Pn junction diode if one side of a single crystal of pure semiconductor ge or si is doped with acceptor impurity atoms and the other side is doped with donor impurity atoms a pn junction is formed as shown in fig p region has a high concentration of holes and n region contains a large number of electrons. A p n junction is the metallurgical boundary between the n and p regions of a semiconductor crystal.

Such junctions show a pronounced rectifying behavior. The width of depletion region alters with the external applied potential. They are also called p n diodes in analogy with vacuum diodes.

I primise this is really simple for you to learn this topic. 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. Why is silicon preferred over germanium in the manufacture of semiconductor devices.

Two important processes occur during the formation of a p n junction diffusion and drift. Hence the region is called as depletion region. During the formation of p n junctiondue to the concentration gradient across p and n sides holes diffuse from p to n p n and electrons diffuse from n to p n p when an electron diffuses from n p it leaves an ionised donor on n sidewhich is immobile as it is bonded to the surrounding atoms.
