Quantum effect creates ‘multi-lane highway’ for electrons

13 Jan 2021
Quantum anomalous Hall effect
Multi-lane highways: the top panel shows stacked alternating layers of magnetic and non-magnetic topological insulators illustrated here as stacked Lego bricks. This allows the Chern number to be changed from one to five. The bottom panel shows experimental measurements of the longitudinal resistance (red) and Hall resistance (blue) demonstrating the QAH effect with Chern number of one to five.

A new multi-layered topological insulator has enabled researchers in the US to achieve fast, highly
