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 ...

In this diagram the upper-left end of the platinum film (shown in light blue) is hotter than the lower-right end. This causes electrons to flow from hot to cold. The spin Nernst effect is shown as ...

Researchers at the University of Manchester’s School of Physics and Astronomy, in collaboration with the Massachusetts Institute of Technology (MIT), have recently published an article in Nature ...

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 ...

Researchers measure how fluid changes the movement of electrons. If you see people walking down a street and coming to a junction, it's difficult to predict which direction they might take. But, if ...

A small crystal of the new material. (Courtesy: Fazel Tafti, Boston College) A team of researchers in the US has discovered that electrons in a transition metal superconductor called ditetrelide flow ...

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 ...

A solid material that conducts electricity perfectly at certain temperatures may also qualify as an almost perfectly flowing liquid. If the result is confirmed, the superconducting material would ...
