In electronics, a junction is the boundary where two distinct materials make contact, most notably the P-N junction in semiconductors where p-type and n-type silicon meet. This interface creates a depletion region that gives diodes and transistors their rectifying and switching properties. In wiring, it simply refers to a node where multiple conductors tie together.
