Control of spin-orbit torques by interface engineering in topological insulator heterostructures

Frédéric Bonell, Minori Goto, Guillaume Sauthier +6

(Bi${}_{1-x}$Sb${}_x$)${}_2$Te${}_3$ topological insulators (TIs) are gathering increasing attention owing to their large charge-to-spin conversion efficiency and the ensuing spin-orbit to…
