The interface at which p-type silicon and n-type silicon make contact with each other. At this coupling point, free electrons (n-type) and holes (p-type) cancel each other and form a "depletion zone" that acts as a non-conductive barrier. The PN junction is one of the primary building blocks of semiconductors.
