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, ...

Last week we covered diodes, specifically thermionic and PN junction diodes. But oh, there are more; and they’re special! One of the the most commonly used ‘specialty’ diode would have to be the metal ...

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 basic building blocks of almost all of today's optoelectronic devices are p–n junction diodes, including photodetectors, light-emitting diodes (LEDs) and lasers. The demonstration of light ...

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 ...

A research team has developed high-performance diamond/ε-Ga 2 O 3 heterojunction pn diodes based on ultrawide bandgap semiconductors, achieving breakdown voltages exceeding 3 kV. This work was ...

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 ...
