Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

At a lecture in 1939, Paul Dirac said that “pure mathematics and physics are becoming ever more closely connected”. He went on to say that the two subjects might unify, with “every branch of pure ...

Electrons in two-dimensional (2D) systems placed under strong magnetic fields often behave in unique ways, prompting the ...

The carrier-resolved photo-Hall effect. Courtesy: O Gunawan/IBM A new technique to extract information on the mobility of electrons and holes in semiconductors has unlocked a long-held secret in the ...
