Reversible tuning of the surface state in a psuedo-binary Bi2(Te-Se)3 topological insulator

Rui Jiang, Lin-Lin Wang, Mianliang Huang +4

We use angle-resolved photoemission spectroscopy to study non-trivial surface state in psuedobinary Bi2Se0.6Te2.3 topological insulator. We show that unlike previously studied bina…
