Charge-density-wave phase transition in1T−TiSe2: Excitonic insulator versus band-type Jahn-Teller mechanism
Abstract
The influence of the charge-density-wave phase transition on the electronic structure of $1T\ensuremath{-}{\mathrm{TiSe}}_{2}$ is studied by means of high-resolution angle-resolved photoemission spectroscopy with synchrotron radiation. We find that both the Se $4p$-type valence band maximum at $\ensuremath{\Gamma}$ and the Ti $3d$-type conduction band minimum at L are lowered upon cooling. Our photoemission results explain the observed anomalies in the transport data and appear to be consistent with the band-type Jahn-Teller mechanism rather than with excitonic electron-hole interaction.

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.
