Thermal conductivity and electrical properties of 6 H silicon carbide

Abstract

Thermal conductivity measurements of 6H SiC crystals were done in the 300–500 K range by means of radiation thermometry. Both p- and n-type crystals with carrier concentrations in the 8×1015 to 1020 cm−3 range were used. For the purest samples it was found that the thermal conductivity normal to the c axis is proportional to T−1.49, the room-temperature value being 3.87 W/cm deg. It was also found that the thermal conductivity parallel to the c axis is about 30% lower than that normal to the c axis. Electrical data in the 100–1000 K range are also presented.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The thermal conductivity of 6H-SiC and 4H-SiC along the [0001] axis is about 20-30% less than along the [1000] axis at room temperature.

    “Finally, the thermal conductivity of 6H-SiC and 4H-SiC along the [0001] axis has been found to be about 20–30% less than the thermal conductivity along the [1000] axis at room temperature1733.”

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.
