Spectroscopic signatures of Kohn anomaly in a topological crystalline insulator
Jingwen Li, Arpita Dutta, Kush Saha +4
Topological crystalline insulators extend the concept of topological insulators by hosting surface states protected by crystallographic symmetry. Their topological phase transition…
Probing chiral symmetry with a topological domain wall sensor
Glenn Wagner, Titus Neupert, Ronny Thomale +5
Chiral symmetry is a fundamental property with profound implications for the properties of elementary particles, that implies a spectral symmetry (i.e. E => -E ) in their dispersio…
Interaction effects in a 1D flat band at a topological crystalline step edge
Glenn Wagner, Souvik Das, Johannes Jung +11
Step edges of topological crystalline insulators can be viewed as predecessors of higher-order topology, as they embody one-dimensional edge channels embedded in an effective three…
A Systematic Investigation of the Coupling between One-Dimensional Edge States of a Topological Crystalline Insulator
Johannes Jung, Artem Odobesko, Robin Boshuis +3
The interaction of spin-polarized one-dimensional (1D) topological edge modes localized along single-atomic steps of the topological crystalline insulator …
Electron-phonon coupling and a resonant-like optical observation of a band inversion in topological crystalline insulator PbSnSe
Mariusz Woźny, Wojciech Szuszkiewicz, Mateusz Dyksik +5
The optical reflectivity of PbSnSe and PbSnSe solid solutions was measured in the THz spectral region energetically corresponding to bulk opti…
Two-valence band electron and heat transport in monocrystalline PbTe-CdTe solid solutions with high Cd content
M. Szot, P. Pfeffer, K. Dybko +10
High quality p-type PbTe-CdTe monocrystalline alloys containing up to 10 at. of Cd are obtained by self-selecting vapor transport method. Mid infrared photoluminescence experim…
