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 ...

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 ...

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 ...

A recent study published in Light: Science & Applications introduced a new method for determining the PN junction depth in a silicon wafer. This technique works at nanometer-scale resolution and is ...
