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…
Towards Topological Quasi-Freestanding Stanene via Substrate Engineering
Domenico Di Sante, Philipp Eck, Maximilian Bauernfeind +5
In search for a new generation of spintronics hardware, material candidates for room temperature quantum spin Hall effect (QSHE) have become a contemporary focus of investigation.…
Testing Topological Protection of Edge States in Hexagonal Quantum Spin Hall Candidate Materials
Fernando Dominguez, Benedikt Scharf, Gang Li +5
We analyze the detailed structure of topological edge mode protection occuring in hexagonal quantum spin Hall (QSH) materials. We focus on bismuthene, antimonene, and arsenene on a…
Correlation-driven charge order in a frustrated two-dimensional atom lattice
Florian Adler, Stephan Rachel, Manuel Laubach +4
We thoroughly examine the ground state of the triangular lattice of Pb on Si(111) using scanning tunneling microscopy. We detect charge-order, accompanied by a subtle structural re…
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…
Triangular Spin-Orbit-Coupled Lattice with Strong Coulomb Correlations: Sn Atoms on a SiC(0001) Substrate
Stefan Glass, Gang Li, Florian Adler +6
Two-dimensional (2D) atom lattices provide model setups for Coulomb correlations inducing competing ground states, partly with topological character. Hexagonal SiC(0001) is an intr…
