A combined inelastic neutron scattering and \textit{ab initio} lattice dynamics study of FeSi
Nazir Khan, Sven Krannich, Dominic Boll +5
The phonon renormalization across the semiconductor-to-metal crossover in FeSi is investigated by inelastic neutron scattering combined with \textit{ab-initio} lattice dynamical ca…
Anomalous transverse optic phonons in SnTe and PbTe -- revisited
Zehua Li, Shasha Li, John-Paul Castellan +5
We present a study of the soft transverse optic phonon mode in SnTe in comparison to the corresponding mode in PbTe using inelastic neutron scattering and ab-initio lattice dynamic…
Band Engineering of Dirac cones in Iron Chalcogenides
Lars Lauke, Rolf Heid, Michael Merz +3
By band engineering the iron chalcogenide Fe(Se,Te) via ab-initio calculations, we search for topological surface states and realizations of Majorana bound states. Proposed topolog…
Competing soft phonon modes at the charge-density-wave transitions in DyTe
M. Maschek, D. A. Zocco, S. Rosenkranz +6
The family of rare-earth tritellurides RTe features charge-density-wave (CDW) order related to strongly momentum-dependent electron-phonon coupling. Similar to other CDW compou…
Designing 3D topological insulators by 2D-Xene (X = Ge, Sn) sheet functionalization in the GaGeTe-type structures
Florian Pielnhofer, Tatiana V. Menshchikova, Igor P. Rusinov +10
State-of-the-art theoretical studies anticipate a 2D Dirac system in the "heavy" analogues of graphene, free-standing buckled honeycomb-like Xenes (X = Si, Ge, Sn, Pb, etc.). Herew…
Pressure effects on crystal and electronic structure of bismuth tellurohalides
I. P. Rusinov, T. V. Menshchikova, I. Yu. Sklyadneva +3
We study the possibility of pressure-induced transitions from a normal semiconductor to a topological insulator (TI) in bismuth tellurohalides using density functional theory and t…
