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…
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…
Elemental Topological Insulator with a Tunable Fermi Level: Strained α-Sn on InSb(001)
A. Barfuss, L. Dudy, M. R. Scholz +16
We report on the epitaxial fabrication and electronic properties of a topological phase in strained α-Sn on InSb. The topological surface state forms in the presence of an unusual…
Hedgehog Spin-texture and Berry's Phase tuning in a Magnetic Topological Insulator
Su-Yang Xu, Madhab Neupane, Chang Liu +18
Understanding and control of spin degrees of freedom on the surfaces of topological materials are key to future applications as well as for realizing novel physics such as the axio…
A topological crystalline insulator (TCI) phase via topological phase transition and crystalline mirror symmetry
Su-Yang Xu, Chang Liu, Nasser Alidoust +18
A Z2 topological insulator protected by time-reversal symmetry is realized via spin-orbit interaction driven band inversion. For example, the topological phase in the Bi-Sb system…
