Surface and bulk Fermiology and band dispersion in non-centrosymmetric BiTeI
Gabriel Landolt, Sergey V. Eremeev, Yury M. Koroteev +11
BiTeI has a layered and non-centrosymmetric structure where strong spin-orbit interaction leads to a giant spin splitting in the bulk bands. Here we present high-resolution angle-r…
Spin correlated electronic state on the surface of a spin-orbit Mott system (Layered Iridates)
Chang Liu, Su-Yang Xu, Nasser Alidoust +13
Novel phases of two dimensional electron systems resulting from new surface or interface modified electronic structures have generated significant interest in material science. We…
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…
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…
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…
Separating the bulk and surface n- to p-type transition in the topological insulator GeBi(4-x)SbxTe7
Stefan Muff, Fabian von Rohr, Gabriel Landolt +5
We identify the multi-layered compound GeBi4Te7 to be a topological insulator with a freestanding Dirac point, slightly above the valence band maximum, using angle-resolved photoem…
