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" ...

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).

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, ...

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 ...

This image shows a state-of-the-art design of GaN p-n junction diodes that has resulted in near-unity ideality factor, avalanche breakdown capability, and record-breaking power performance. Insets ...

One of the oldest and one of the newest semiconductors, Schottky diode use can be traced back to before 1900 where crystal detectors were all effectively Schottky diodes. Today, the new silicon ...

Si LSI manufacturing technology is essential as the foundation of modern society. However, there was no wafer-scale technology for rapid, non-destructive, and non-contact evaluation of the internal ...
