Pn junction

Flat 2D textbook-style cross-sectional diagram of a semiconductor p–n junction shown as a rectangular solid block split into two adjoining regions. The left half is a p-type region tinted warm red or pink and labeled p or p-type, while the right half is an n-type region tinted cool blue and labeled n or n-type. The two halves meet at a sharp vertical interface at the center. A narrow pale band straddling the interface represents the depletion region, optionally with small fixed ion or dopant charge symbols on each side near the boundary. Clean geometric shapes, minimal educational clipart style, and a simple technical cross-section appearance.
