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.
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 (
) relation.
Electronic component
An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singula ...
s employing rectifying junctions include
p–n diodes,
Schottky diodes and
bipolar junction transistors.
