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 ...

Physicists have directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results have applications in developing new, low-resistance materials, ...

A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

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

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 ...

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 ...

Table 1 Properties of 2DEG samples, measured in a Hall bar configuration. Sample A was grown by the commercial grower IQE. Sample B was grown by H. Shtrikman. Sample C was grown by L. N. Pfeiffer and ...

Time to retire the old soldering iron? In the “atomtronic” circuits pictured on the right, it is atoms, not electrons, that flow. Such circuits could form the basis for ultra-sensitive gyroscopes.
