Hyperphysics pn junction
Web13 jan. 2024 · A p–n junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains an excess of holes, while the "n" (negative) side contains an excess of electrons in the outer shells of the electrically neutral atoms there. This allows … WebNear the junction is a region having no free charge carriers. This region, called the depletion layer, behaves as an insulator. The most important characteristic of p - n junctions is that they rectify. Part A of the figure shows the current-voltage characteristics of a typical silicon p - n junction. When a forward bias is applied to the p - n ...

WebA p–n junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains an excess of holes, while the "n" (negative) side contains an excess of electrons in the outer shells of the electrically neutral atoms there. WebWhen the junction is between different semiconductors, the junction is labelled either Pn or Np, where the capital letter denotes the doping type of the semiconductor with the higher bandgap. Semiconductor/semiconductor junctions play a crucial role in solar cells, LEDs, bipolar transistors, and HJFETs, and are prominent also in MOSFETs.
