Thermal conductivity of graphene and graphite

Alofi, A., Srivastava, G. P.·2013·Physical Review B

Abstract

The thermal conductivities of graphene and graphite are computed within the framework of Callaway's effective relaxation time theory. Analytical expressions derived by Nihira and Iwata for phonon dispersion relations and vibrational density of states are employed, based on the semicontinuum model proposed by Komatsu and Nagamiya. The conductivity of graphene is predicted to be higher than the in-plane conductivity of graphite for all temperatures. Incorporation of the ${}^{13}$C isotope can be expected to produce significant reduction in the conductivity of graphene in the temperature range 50--300 K. In the presence of tensile strain on graphene, the specific heat increases, but the conductivity can decrease or increase depending on the level of the purity and temperature of the sample.

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.
