PN junctions are semiconductor devices formed by joining two pieces of semiconductor material with opposite types of electrical conductivity. PN junctions are used in a wide variety of electronic devices, including diodes, transistors, solar cells, and light-emitting diodes (LEDs). PN junctions form when a P-type semiconductor with positive charge carriers is brought into contact with an N-type semiconductor with negative charge carriers. The resulting structure creates a region of depletion, where charge carriers are depleted from the region near the junction. This depletion region forms the basis of the PN junction's electrical properties.
Semiconductor Materials
Semiconductors are materials that can conduct electricity under certain conditions, but not under others. The electrical conductivity of a semiconductor can be controlled by the addition or removal of dopants, which are impurities that can change the semiconductor's electrical properties. PN junctions form when two semiconductor materials with opposite types of conductivity are joined together.
