Pn junction is one of the most important structures in today’s semiconductor technology used in transistors, FET and many types of integrated circuits. In our previous articles, we have seen  p-n junction formation from a p-type and n-type semiconductor and Semiconductor electronics. We have also learned about diffusion current, drift current and depletion region. Here we are going to explain how p-n junction diode characteristics. [Image source] P-n junction diode: To understand the behavior of p-n junction we make it conducting by applying an external voltage over a range of 0v, 5v, 10v and determine how the current passed through Read More …

Pn Junction : Basic theory

formation of pn junction image

Pn junctions are formed by joining two different type of semiconductor material i.e. p-type semiconductor on one side and n-type semiconductor on another side. In this article, we are going to explain you about p-n juenction formation, phenomena of p-n junction formation and basic equations. Have a look at it. It is discovered by the American physicist Russell Ohl at Bell laboratories. In p-type semiconductor holes are majority carriers and electrons are minority carriers while in n-type semiconductor electrons are majority carriers and holes are minority carriers i.e. one end has excess of electrons and other has excess of holes. P-n Read More …
