Discovery of highly spin-polarized conducting surface states in the strong spin-orbit coupling semiconductor Sb${}_2$Se${}_3$

Shekhar Das, Suman Kamboj, Anshu Sirohi +4

Majority of the A${}_2$B${}_3$ type chalcogenide systems with strong spin-orbit coupling, like Bi${}_2$Se${}_3$, Bi${}_2$Te${}_3$ and Sb${}_2$Te${}_3$ etc., are topological insulators. One importa…
