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 ...

What is a P-N Junction? A p-n junction is a fundamental building block of modern electronics, formed by joining together two types of semiconductor materials: p-type (positive) and n-type (negative).
