Sputtering induced re-emergence of the topological surface state in Bi${}_2$Se${}_3$

Raquel Queiroz, Gabriel Landolt, Stefan Muff +9

We study the fate of the surface states of Bi${}_2$Se${}_3$ under disorder with strength larger than the bulk gap, caused by neon sputtering and nonmagnetic adsorbates. We find that ne…
