Kohn Anomalies and Electron-Phonon Interactions in Graphite
Open accessAbstract
We demonstrate that graphite phonon dispersions have two Kohn anomalies at the $\ensuremath{\Gamma}\mathrm{\text{\ensuremath{-}}}{E}_{2g}$ and $\mathbf{K}\mathrm{\text{\ensuremath{-}}}{A}_{1}^{\ensuremath{'}}$ modes. The anomalies are revealed by two sharp kinks. By an exact analytic derivation, we show that the slope of these kinks is proportional to the square of the electron-phonon coupling (EPC). Thus, we can directly measure the EPC from the experimental dispersions. The $\ensuremath{\Gamma}\mathrm{\text{\ensuremath{-}}}{E}_{2g}$ and $\mathbf{K}\mathrm{\text{\ensuremath{-}}}{A}_{1}^{\ensuremath{'}}$ EPCs are particularly large, while they are negligible for all the other modes at $\ensuremath{\Gamma}$ and $\mathbf{K}$.

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.
