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 ( I − V {\displaystyle I-V} ) relation. Electronic components employing rectifying junctions include p–n diodes, Schottky diodes and bipolar junction transistors.
