Observation of Chiral character deep in the topological insulating regime in Bi${}_{1-x}$Sb${}_x$

Amit, R. K. Gopal, Yogesh Singh

Bi${}_{1-x}$Sb${}_x$ is a topological insulator (TI) for $x\approx 0.03$--$0.20$. Close to the Topological phase transition at $x=0.03$, a magnetic field induced Weyl semi-metal (W…
