Intrinsic quantized anomalous Hall effect in a moiré heterostructure

Phys.org   -   Scientific News Websites

The quantum anomalous Hall (QAH) effect can combine topology and magnetism to produce precisely quantized Hall resistance at zero magnetic field (an environment carefully screened from magnetic fields). In a recent report on Science, M. Serlin and...
