A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p -type semiconducting layer to an n -type semiconducting layer.
Tutorial Summary. The PN junction region of a Junction Diode has the following important characteristics: Semiconductors contain two types of mobile charge carriers, “Holes” and “Electrons”. The holes are positively charged while the electrons negatively charged.
Apr 15, 2021 · A diode is a specialized electronic component that acts as a one-way switch. It conducts electric current in only one direction and restricts current from the opposite direction. A diode is reverse biased when it acts as an insulator and is forward biased when it allows current to flow. A diode has two terminals, the anode and the cathode.
May 15, 2024 · P-N Junction. Inside a semiconductor, a p-n junction is an interface or a border between two semiconductor material types, namely the p-type and the n-type. The semiconductor’s p-side, or positive side, has an excess of holes, whereas the n-side, or negative side, has an excess of electrons.
A p–n junction diode. The circuit symbol is also shown. A p–n junction is a combination of two types of semiconductor materials, p-type and n-type, in a single crystal. The "n" (negative) side contains freely-moving electrons, while the "p" (positive) side contains freely-moving electron holes.
A PN-junction is formed when an N-type material is fused together with a P-type material creating a semiconductor diode. This tutorial about PN junction theory shows that when silicon is doped with small amounts of Antimony, an N-type semiconductor material is formed, and when the same silicon material is doped with small amounts of Boron, a P ...
