A new "optoexcitonic switch" already achieves state-of-the-art performance over current electronics and could serve as the ...

If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...

In solar cells, solar radiation boosts electrons to higher energy states, thereby releasing them from their atomic bonds as electricity begins to flow. Scientists have now developed a novel method to ...

A new type of switch sends electrons propagating in opposite directions along the same paths – without ever colliding with each other. The switch works by controlling the presence of so-called ...

Diffusion and hydrodynamic flow There are two main types of energy transport that underlie the researchers' concept: hydrodynamic flow, a collective kinetic process where the individual components of ...

In a strange metal (translucent box), electrons (blue marbles) lose their individuality and melt into a featureless, liquid-like stream. We all learned that electricity is caused by electrons moving ...

On a quest to discover new states of matter, a team of scientists has found that electrons on the surface of specific materials act like miniature superheroes, relentlessly dodging the cliff-like ...

The most obvious advantage of superconductors – materials that offer no electrical resistance to the flow of electrons – in electronic circuits is that they don’t produce any wasteful heating, which ...

A team of researchers from Boston College has created a new metallic specimen where the motion of electrons flows in the same way water flows in a pipe—fundamentally changing from particle-like to ...

Spin electronics, or “spintronics” promises to revolutionize computing. We’ve covered numerous breakthroughs in the field including controlling the spin of electrons, manipulating single electrons ...

In graphene, electrons move in strange ways. Their unusual and fluid-like behavior was observed by scientists at the National Graphene Institute, leading to a new wave of studies related to the ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...
