Deskripsi

Topological edge states offer the prospect of dissipationless transport for nanoelectronics, but a precise method to spatially engineer such nanoscale conducting channels is still lacking. Here, the authors demonstrate patterning of topological boundary states in Sb2Te3 using a focused ion beam to create amorphous, topologically trivial regions.
