P-N Junction. p-n junction diodes are made up of two adjacent pieces of p-type and n-type semiconducting materials. p-type and n-type materials are simply semiconductors, such as silicon (Si) or germanium (Ge), with atomic impurities; the type of impurity present determines the type of the semiconductor.

http://hyperphysics.phy-astr.gsu.edu/hbase/Solids/pnjun.html WebFor silicon diodes, the built-in potential is approximately 0.7 V. Thus, if an external current is passed through the diode, about 0.7 V will be developed across the diode such that the P-doped region is positive with respect to the N-doped region and the diode is said to be "turned on" as it has a forward bias. Therefore, 2.3 V - 1.6 V = 0.7 V.

Semiconductors utilize the fact that different materials (dopents) contain a free electron or a missing electron to …
A p–n junction diode allows electric charges to flow in one direction, but not in the opposite direction; negative charges (electrons) can easily flow through the junction from n to p but not from p to n, and the reverse is true for holes. See more 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 … See more Size of depletion region For a p–n junction, let $${\displaystyle C_{A}(x)}$$ be the concentration of negatively-charged acceptor atoms and where See more The p-n junction is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy (growing a layer of crystal doped with … See more • Alloy-junction transistor • Capacitance–voltage profiling • Deep-level transient spectroscopy See more The p–n junction possesses a useful property for modern semiconductor electronics. A p-doped semiconductor is relatively conductive. The same is true of an n-doped semiconductor, but the junction between them can become depleted See more In the above diagrams, contact between the metal wires and the semiconductor material also creates metal–semiconductor junctions called Schottky diodes.
