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 ...

A light pulse redirects electrons in an ultrathin layered material, creating a stable new state without heat or damage and ...

Physicists have now observed electron whirlpools. Theorists have long predicted electrons should exhibit this hallmark of fluid flow; the findings could inform the design of more efficient electronics ...

Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny ...

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: ...

The direction of electron flow in molecular optoelectronic devices is dictated by charge transfer between a molecular excited state and an underlying conductor or semiconductor. For those devices, ...

When light hits the surface of some materials, namely those exhibiting a property known as photoresistance, it can induce changes in their electrical conductivity. Graphene is among these materials, ...

If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...
