What is a P-N Junction? A p-n junction is a fundamental building block of modern electronics, formed by joining together two types of semiconductor materials: p-type (positive) and n-type (negative).

The PN junction is one of the primary building blocks of semiconductors. Diodes and Thyristors A diode (one way valve) is a PN junction with p-type on one side and n-type on the other.

Insets show a GaN p-n diode fabricated on a high-quality bulk GaN substrate and light emission from the junction under forward bias.

Semiconductors can be doped with other materials to become p-type or n-type. A p-n junction diode can be forward or reverse bias. LEDs are forward bias diodes that produce photons of light.

Bipolar devices, such as pn diodes and bipolar junction transistors, hold promising potential in the high-power electronics industry due to their ability to withstand reverse voltage currents.

This study presents a non-destructive technique for PN junction depth measurement in silicon wafers, utilizing terahertz waves for nanometer-scale resolution.

Solids can be categorised into conductors, semiconductors or insulators by their ability to conduct electricity. Electron band theory explains differences in conduction. Semiconductors can be doped ...
