TL;DR: In this article , the authors measured the peak thermal conductivity of boron arsenide (BAs) at temperatures between 120 and 150 K and reported that the peak temperature of BAs is at most 4.16m in two samples and 5m in another.
Journal ArticleDOI
Development of a high-temperature (295–900 K) Seebeck coefficient Standard Reference Material
TL;DR: In this article, the authors report the development of a high-temperature Seebeck coefficient standard reference material (SRM) for use in instrument validation and interlaboratory data comparison in the temperature range of 295-900 K to support the research, development, and production of materials and devices related to thermoelectric-based energy conversion applications.

TL;DR: In this paper, the core-shell-ed structures of paramagnetic microspheres were successfully synthesized by electroless plating technique and the surface morphology and coreshelled structures were examined by scanning electron microscopy as well as optical microscopy.
The effect of shallow vs. deep level doping on the performance of thermoelectric materials
TL;DR: In this paper, it is shown that different impurity levels (shallow or deep) will be desired to optimize the efficiency of a thermoelectric material, depending on the material type and temperature range of operation.
