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 interface at which p-type silicon and n-type silicon make contact with each other. At this coupling point, free electrons (n-type) and holes (p-type) cancel each other and form a "depletion zone" ...

Last week we covered diodes, specifically thermionic and PN junction diodes. But oh, there are more; and they’re special! One of the the most commonly used ‘specialty’ diode would have to be the metal ...

Find a downloadable version of this story in pdf format at the end of the story. Silicon Schottky diodes are used in power applications because of their low forward voltage drop, which allows lower ...

There are 8 different types of diodes that are available for use in electronics design. The various types of diodes enable different kinds of application specifications to be met. As a result of the ...

a, Schematic illustration of the buried channel transistor structure. b, THz emission from the PN junction. Ultrafast photocarrier transport due to the built-in electric field (drift current) ...

Technological advances in the electronics industry have resulted in our digital cameras, computers, and cell phones drastically reducing in size. In order to maintain this momentum, there is a strong ...

Although they are a simple device, diodes do have a number of traits to consider. These traits are often application dependent. Some applications include: rectifiers, signal ORing, transistor turn off ...

In conventional organic solar cells, the electrons exhibit their particle-nature and need to jump between organic molecules in the cell. The conductivity is, therefore, lower than that of crystalline ...
