Metallicity-driven polar transitions in topological epilayers
Eduardo D. Stefanato, Nicolas M. Kawahala, Bianca A. Kawata +3
Polar metals, materials that exhibit both electric polarization and high conductivity, can also host topological phases. Because free carriers strongly suppress distortive polar or…
Terahertz Cavity Phonon Polaritons in Lead Telluride in the Deep-Strong Coupling Regime
Andrey Baydin, Manukumara Manjappa, Sobhan Subhra Mishra +9
Lead telluride is an important thermoelectric material due to its large Seebeck coefficient combined with its unusually low thermal conductivity that is related to the strong anhar…
Chiral Phonons with Giant Magnetic Moments in a Topological Crystalline Insulator
Felix G. G. Hernandez, Andrey Baydin, Swati Chaudhary +10
We have studied the magnetic response of transverse optical phonons in PbSnTe films. Polarization-dependent terahertz magnetospectroscopy measurements revealed Zeeman…
Magnetic Control of Soft Chiral Phonons in PbTe
Andrey Baydin, Felix G. G. Hernandez, Martin Rodriguez-Vega +10
PbTe crystals have a soft transverse optical phonon mode in the terahertz frequency range, which is known to efficiently decay into heat-carrying acoustic phonons, resulting in ano…
Incipient antiferromagnetism in the Eu-doped topological insulator BiTe
Abdul Tcakaev, Volodymyr B. Zabolotnyy, Celso I. Fornari +14
Rare earth ions typically exhibit larger magnetic moments than transition metal ions and thus promise the opening of a wider exchange gap in the Dirac surface states of topological…
Morphology Control in van der Waals Epitaxy of Bismuth Telluride Topological Insulators
Celso I. Fornari, Eduardo Abramof, Paulo H. O. Rappl +2
Bismuth telluride have regained significant attention as a prototype of topological insulator. Thin films of high quality have been investigated as a basic platform for novel spint…
