Phonon Dispersion in Graphite
Abstract
We measured the dispersion of the graphite optical phonons in the in-plane Brillouin zone by inelastic x-ray scattering. The longitudinal and transverse optical branches cross along the $\ensuremath{\Gamma}\mathrm{\text{\ensuremath{-}}}K$ as well as the $\ensuremath{\Gamma}\mathrm{\text{\ensuremath{-}}}M$ direction. The dispersion of the optical phonons was, in general, stronger than expected from the literature. At the $K$ point the transverse optical mode has a minimum and is only $\ensuremath{\approx}70\text{ }\text{ }{\mathrm{c}\mathrm{m}}^{\ensuremath{-}1}$ higher in frequency than the longitudinal mode. We show that first-principles calculations describe very well the vibrational properties of graphene once the long-range character of the dynamical matrix is taken into account.

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.
