Semiconductors are materials that have their electric conductivity between conductors and insulators. the properties and conductivity of an intrinsic semiconductor (pure semiconductor) can be altered by adding impurities; this process of adding impurities into a semiconductor is known as doping. How doping a pure silicon crystal dramatically changes electrical conductivity – the fundamental idea in underlying the use of semiconductors in the implementation of electronic devices. If one side of crystal pure semiconductor si(silicon) or ge(germanium) is doped with acceptor impurity atoms and the other side is doped with donor impurity atoms , a pn junction is formed as shown in figure.p region has high concentration of holes and n region contains large number of electrons.

Doping means the introduction of impurities into a semiconductor crystal to the de fined modification of conductivity. two of the most important materials silicon can be doped with, are boron (3 valence electrons = 3 valent) and phosphorus (5 valence electrons = 5 valent). Recombination and generation are always happening in semiconductors, both optically and thermally, and their rates are in balance at equilibrium. the product of the rate becomes greater than the recombination rate, again driving the system back towards equilibrium. The p − n junction is formed when the two different sides of semiconductor are doped, respectively with holes (for example, al for si) and electrons (for example, p for si).
