Topological nature of theFeSe0.5Te0.5superconductor
Open accessAbstract
We demonstrate, using first-principles calculations, that the electronic structure of ${\mathrm{FeSe}}_{1\ensuremath{-}x}{\mathrm{Te}}_{x}\phantom{\rule{0.28em}{0ex}}(x=0.5)$ is topologically nontrivial and characterized by an odd ${\mathbb{Z}}_{2}$ invariant and Dirac cone type surface states, in sharp contrast to the end member FeSe $(x=0)$. This topological state is induced by the enhanced three-dimensionality and spin-orbit coupling due to Te substitution (compared to FeSe), and characterized by a band inversion at the $Z$ point of the Brillouin zone, which is confirmed by our ARPES measurements. The results suggest that the surface of ${\mathrm{FeSe}}_{0.5}{\mathrm{Te}}_{0.5}$ may support a nontrivial superconducting channel in proximity to the bulk.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
