The Quantum Hall Effect was first observed in 1980 by Klaus von Klitzing, for which he was awarded the Nobel Prize in Physics in 1985. It occurs in two-dimensional electron gases found in ...

Until now, the zero magnetic field Quantum Anomalous Hall effect only occurred at very low currents. This device can change that. The precise measurement of electrical resistance is essential in ...
