Using a PN-junction diode for temperature measurement usually depends on its 2‑mV/K temperature coefficient. Conventionally, you must amplify and digitize this voltage with an ADC before you can use ...

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 ...

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 ...

A p-n junction is an interface or boundary between p-type and n-type semiconductor materials within a single semiconductor crystal. The positive (p) side contains excess holes, while the negative (n) ...
