Nonequilibrium spin texture within a thin layer below the surface of current-carrying topological insulator Bi${}_2$Se${}_3$: A first-principles quantum transport study

Po-Hao Chang, Troels Markussen, Søren Smidstrup +2

We predict that unpolarized charge current injected into a ballistic thin film of prototypical topological insulator (TI) Bi${}_2$Se${}_3$ will generate a {\it noncollinear spin textur…
