Electrical junction

An electrical junction is a point or area where (a) two or more conductors or (b) different semiconducting regions of differing electrical properties make physical contact.

[1] Electrical junctions types include thermoelectricity junctions, metal–semiconductor junctions and p–n junctions.

Junctions are either rectifying or non-rectifying.

Non-rectifying junctions comprise ohmic contacts, which are characterised by a linear current–voltage (

Electronic components employing rectifying junctions include p–n diodes, Schottky diodes and bipolar junction transistors.
