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" ...

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, ...

In this online engineering specialization, you will master the fundamentals of semiconductors and evaluate the performance of electronic devices by completing courses in semiconductor physics, PN ...

A new terahertz technique reveals nanometer-scale PN junction depths in silicon chips, enabling faster, non-contact inspection for advanced semiconductor manufacturing. (Nanowerk News) Silicon ...

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 ...

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 ...

In the past few years, the research effort on 2D materials has rapidly increased, driven by the great variety of layered materials and their exceptional properties when reduced to a few atomic layers ...

Researchers recently observed negative refraction of electrons in graphene PN junctions. The creation of PN junctions in graphene is quite interesting, itself. Negative refraction isn’t a new idea. It ...
