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 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 ...

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 ...

A p-n junction is an interface or boundary between p-type and n-type semiconductor materials within a single semiconductor crystal. The positive (p) side contains excess holes, while the negative (n) ...

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).

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 ...

a, Schematic illustration of the buried channel transistor structure. b, THz emission from the PN junction. Ultrafast photocarrier transport due to the built-in electric field (drift current) ...
