Observation of room temperature excitons in an atomically thin topological insulator
Marcin Syperek, Raul Stühler, Armando Consiglio +10
Optical spectroscopy of ultimately thin materials has significantly enhanced our understanding of collective excitations in low-dimensional semiconductors. This is particularly ref…
Lifting topological protection in a quantum spin Hall insulator by edge coupling
Raul Stühler, André Kowalewski, Felix Reis +7
The scientific interest in two-dimensional topological insulators (2D TIs) is currently shifting from a more fundamental perspective to the exploration and design of novel function…
Tailoring the topological surface state in ultrathin -Sn (111) films
Victor A. Rogalev, Felix Reis, Florian Adler +11
We report on the electronic structure of -Sn films in the very low thickness regime grown on InSb(111)A. High-resolution low photon energies angle-resolved photoemission (ARPES)…
Non-trivial topological valence bands of common diamond and zinc-blende semiconductors
Tomáš Rauch, Victor A. Rogalev, Maximilian Bauernfeind +11
The diamond and zinc-blende semiconductors are well-known and have been widely studied for decades. Yet, their electronic structure still surprises with unexpected topological prop…
Tomonaga-Luttinger liquid in the edge channels of a quantum spin Hall insulator
R. Stühler, F. Reis, T. Müller +5
Topological quantum matter is characterized by non-trivial global invariants of the bulk which induce gapless electronic states at its boundaries. A case in point are two-dimension…
A new paradigm for the quantum spin Hall effect at high temperatures
Gang Li, Werner Hanke, Ewelina M. Hankiewicz +5
The quantum spin Hall effect (QSHE) has formed the seed for contemporary research on topological quantum states of matter. Since its discovery in HgTe/CdTe quantum wells and AlGaAs…
The topological surface state of -Sn on InSb(001) as studied by photoemission
M. R. Scholz, V. A. Rogalev, L. Dudy +14
We report on the electronic structure of the elemental topological semimetal -Sn on InSb(001). High-resolution angle-resolved photoemission data allow to observe the topological…
Double Band Inversion in -Sn: Appearance of Topological Surface States and the Role of Orbital Composition
Victor A. Rogalev, Tomáš Rauch, Markus R. Scholz +9
The electronic structure of \graySn(001) thin films strained compressively in-plane was studied both experimentally and theoretically. A new topological surface state (TSS) located…
Bismuthene on a SiC Substrate: A Candidate for a New High-Temperature Quantum Spin Hall Paradigm
F. Reis, G. Li, L. Dudy +6
Quantum spin Hall (QSH) materials promise revolutionary device applications based on dissipationless propagation of spin currents. They are two-dimensional (2D) representatives of…
Signatures of Dirac fermion-mediated magnetic order
Paolo Sessi, Felix Reis, Thomas Bathon +3
The spin-momentum locking of topological states offers an ideal platform to explore novel magneto-electric effects. These intimately depend on the ability to manipulate the spin te…
