How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

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" ...

This course presents in-depth discussion and analysis of pn junction and metal-semiconductor contacts including equilibrium behavior, current and capacitance responses under bias, breakdown, ...

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 ...

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 ...
