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).

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 ...

The basic building blocks of almost all of today's optoelectronic devices are p–n junction diodes, including photodetectors, light-emitting diodes (LEDs) and lasers. The demonstration of light ...
