Electrical junction

{{for|the enclosure housing electrical connections|Junction box}} 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.<ref>{{Cite book |url=http://oxfordreference.com/view/10.1093/acref/9780198725725.001.0001/acref-9780198725725 |title=A Dictionary of Electronics and Electrical Engineering |date=2018 |publisher=Oxford University Press |isbn=978-0-19-872572-5 |editor-last=Butterfield |editor-first=Andrew J. |volume=1 |language=en |doi=10.1093/acref/9780198725725.001.0001 |editor-last2=Szymanski |editor-first2=John}}</ref> 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 (<math>I-V</math>) relation. Electronic components employing rectifying junctions include p–n diodes, Schottky diodes and bipolar junction transistors.
