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" ...

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 ...

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 ...

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, ...

For the standard junction diode, there are two operating regions and three possible biasing conditions. There is no external potential energy applied to the P-N junction when a diode is connected in a ...

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).

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 ...

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 ...
