(civil engineering)
A point of intersection of roads or highways, especially where one terminates.

(electronics)
A region of transition between two different semiconducting regions in a semiconductor device, such as a pn junction, or between a metal and a semiconductor.
(electromagnetism)
A fitting used to join a branch waveguide at an angle to a main waveguide, as in a tee junction. Also known as waveguide junction.

junction

The point at which two elements make contact. In a transistor, a junction is the point where an N-type material makes contact with a P-type material.
