A new method by Penn State researchers conveniently changes the direction of electron flow in materials that exhibit the quantum anomalous Hall (QAH) effect — a phenomenon in which the flow of ...

The presence of impurities or defects, also known as disorder, in a metal could hinder the flow of free electrons. Beyond a critical value, such disorder could completely stop electron flow, turning ...

Scientist have found they can turn on and off the flow of current in a bismuth crystal subjected to a high magnetic field, making a new type of controllable quantum wire. Princeton researchers have ...

Spintronics, or spin-electronics, is a revolutionary approach to information processing that utilizes the intrinsic angular ...

Researchers in South Korea have created magnetic nanohelices that can control electron spin at room temperature. Spintronics, ...

Physicists in the US have shown that light hitting a conductive metal surface at an angle can cause free electrons in the metal to move either in the same direction or in the opposite direction as the ...

Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the ...

If you ever wished electrons would just behave, this one’s for you. A team from Tohoku, Osaka, and Manchester Universities has cracked open an interesting phenomenon in the chiral helimagnet α-EuP 3: ...

A river made of graphene with the electrons flowing like water. Courtesy: Ryan Allen and Peter Allen, Second Bay Studios Electrons can behave like a viscous liquid as they travel through a conducting ...

A new nanostructure acts like a wire and switch that can, for the first time, control and direct the flow of quantum ...

Researchers at MIT have observed “electron whirlpools” for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics. Like water, ...
