The Hall effect is a conduction phenomenon discovered by physicist Edwin Herbert Hall that describes the development of a transverse electric field in solid materials carrying electric current that are placed in a magnetic ...
A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, ...
