The revelation that electrons in the single-atom-thick material known as graphene can act much like a frictionless fluid is a ...

The electrical resistance of a metal is caused by electrons being scattered from impurities in the material’s atomic lattice or from lattice vibrations called phonons. However, it is not affected by ...

Scientists have observed a quantum fluid of electrons in graphene for the first time, showing near-perfect fluid behaviour and shedding light on a quantum physics puzzle. In a collaborative effort, ...

Conventional wisdom holds that an electric current never returns to its source nor follows a circular path. Instead, it flows from one electrode to another following a local electric field, obeying ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

Coulomb blockade is a phenomenon in which the flow of electrons through a nanostructure, such as a quantum dot or a single-electron transistor, is restricted due to the electrostatic repulsion between ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

Scientists observed record-breaking electron mobility — seven times higher than in conventional semiconductors — with a material made from the same elements as quartz and gold. When you purchase ...

(Nanowerk News) CEA-Leti research scientists have demonstrated that electrons and other charge carriers can move faster in germanium tin than in silicon or germanium, enabling lower operation voltages ...

You turn on a switch and the light switches on because electricity 'flows'. The usual perception is that this is like opening a faucet and the water starts to flow. But this analogy is misleading. The ...
