Heat capacity and thermal conductivity of hexagonal pyrolytic boron nitride

Sichel, E. K., Miller, R. E., Abrahams, M. S., Buiocchi, C. J.·1976·Physical Review B

Abstract

We have measured the heat capacity and thermal conductivity of the layered material hexagonal pyrolytic boron nitride from 2 to 10 K by a pulse-heating technique. The thermal conductivity has also been determined by a steady-state technique from 1.5 to 350 K. At low temperatures, the heat capacity has a ${T}^{3}$ dependence and the thermal conductivity a ${T}^{2.4}$ dependence. Crystallite size was found from transmission electron micrographs. The influence of dislocations on the thermal conductivity is discussed.

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.
