Topological current divider in a chern insulator junction

HIGHLIGHTS

• who: Dmitry Ovchinnikov from the (UNIVERSITY) have published the research: Topological current divider in a Chern insulator junction, in the Journal: (JOURNAL) of 26/04/2022
• what: The authors report a chiral edge-current divider based on Chern insulator junctions formed within the layered topological magnet MnBi2Te4. The authors focus here on a device (Device 1) which has a 4-layer part (Domain I) and a 6-layer part (Domain II) (Supplementary Fig 1).

SUMMARY

The authors find that in a device containing a boundary between regions of different thickness, topological . . .
