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" ...

Formed at the boundary between an N-type and P-type semiconductor is a P-N Junction which is created by doping a single crystal of semiconductor. The nature of the P-N junction is one of the crucial ...

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 ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley wanted ...

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 ...

SAXONBURG, Pa., Sept. 05, 2025 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, announced today its membership in the Diode Technology Working Group within the STARFIRE ...

Solids can be categorised into conductors, semiconductors or insulators by their ability to conduct electricity. Electron band theory explains differences in conduction. Semiconductors can be doped ...
