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 ...

A material cooled near absolute zero produced an electrical signal that physics said should not exist, revealing a new kind ...

Diamond detection A sensor based on NV centres has been used to measure electrical currents in the heart of a rat. (Courtesy: iStock/Gizmo) A diamond-based sensor that maps out the subtle electrical ...

Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...

Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though ...

This course introduces basic concepts of the quantum theory of solids and presents the theory describing the carrier behaviors in semiconductors. The course balances fundamental physics with ...
