=== Homojunctions ===
'''[[Homojunction]]s''' occur when two differently doped semiconducting materials are joined. For example, a configuration could consist of p-doped and n-doped [[germanium]]. This results in an exchange of electrons and holes between the differently doped semiconducting materials. The n-doped germanium would have an excess of electrons, and the p-doped germanium would have an excess of holes. The transfer occurs until an equilibrium is reached by a process called [[recombination (physics)|recombination]], which causes the migrating electrons from the n-type to come in contact with the migrating holes from the p-type.<ref>{{Cite web |date=2016-07-28 |title=Electron-Hole Recombination |url=https://eng.libretexts.org/Bookshelves/Materials_Science/Supplemental_Modules_(Materials_Science)/Electronic_Properties/Electron-Hole_Recombination |access-date=2024-04-01 |website=Engineering LibreTexts |language=en}}</ref> The result of this process is a narrow strip of immobile [[ion]]s, which causes an [[electric field]] across the junction.<ref name="Feynman" /><ref name="Neamen"
