Sputtering induced re-emergence of the topological surface state in BiSe
Raquel Queiroz, Gabriel Landolt, Stefan Muff +9
We study the fate of the surface states of BiSe under disorder with strength larger than the bulk gap, caused by neon sputtering and nonmagnetic adsorbates. We find that ne…
Unconventional transformation of spin Dirac phase across a topological quantum phase transition
Su-Yang Xu, Madhab Neupane, Ilya Belopolski +15
The topology of a topological material can be encoded in its surface states. These surface states can only be removed by a bulk topological quantum phase transition into a trivial…
Surface versus bulk contributions to the giant Rashba splitting in the ferroelectric α-GeTe(111) semiconductor
J. Krempaský, H. Volfová, S. Muff +14
In systems with broken inversion symmetry spin-orbit coupling (SOC) yields a Rashba-type spin splitting of electronic states, manifested in a k-dependent splitting of the bands. Wh…
Response of the topological surface state to surface disorder in TlBiSe
Florian Pielmeier, Gabriel Landolt, Bartosz Slomski +12
Through a combination of experimental techniques we show that the topmost layer of the topo- logical insulator TlBiSe as prepared by cleavage is formed by irregularly shaped Tl…
