Definitions for p-n junction
This page provides all possible meanings and translations of the word p-n junction
the junction between a p-type semiconductor and an n-type semiconductor
"a p-n junction has marked rectifying characteristics"
An interface between a p-type and n-type semiconductor; used to create junction diodes and junction transistors
A p–n junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor. It is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy. If two separate pieces of material were used, this would introduce a grain boundary between the semiconductors that would severely inhibit its utility by scattering the electrons and holes. p–n junctions are elementary "building blocks" of most semiconductor electronic devices such as diodes, transistors, solar cells, LEDs, and integrated circuits; they are the active sites where the electronic action of the device takes place. For example, a common type of transistor, the bipolar junction transistor, consists of two p–n junctions in series, in the form n–p–n or p–n–p. The discovery of the p–n junction is usually attributed to American physicist Russell Ohl of Bell Laboratories. A Schottky junction is a special case of a p–n junction, where metal serves the role of the p-type semiconductor.
