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" ...

Photoelectrochemical (PEC) water splitting is a potentially feasible strategy for converting solar energy to green hydrogen. However, current PEC systems suffer from relatively low charge separation ...

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).

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 ...

The feature size of silicon-based transistors is approaching the theoretical limit, which puts forward higher requirements for the atomic level manufacturing of semiconductors. The basic idea of ...

The electronic properties of graphene films are directly affected by the characteristics of the substrates on which they are grown or to which they are transferred. Researchers are taking advantage of ...

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 ...

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 ...
