“…Thermal conductivity, thermoelectric power and electrical resistivity were measured using a four-probe method with a parallelepiped sample cut from the sintered pellet. The measurements were done on sample cooling and warming using a close-cycle cryostat down to 3.5 K, the detailed description of the cell including calibration is described elsewhere [13]. For the XANES measurements, a part of the samples were pulverized, mixed with 3N boron nitride (BN) powder with proper molar ratios in order to optimize the absorption and pelletized 6 mm in diameter and 0.5 mm in thickness.…”

We present an extensive investigation (magnetic, electric and thermal measurements and X-ray absorption spectroscopy) of the Pr 0.5 Ca 0.5 CoO 3 and (Pr 1-y Y y ) 0.7 Ca 0.3 CoO 3 (y = 0.0625 -0.15) perovskites, in which a peculiar metal-insulator (M-I) transition, accompanied with pronounced structural and magnetic anomalies, occurs at 76 K and 40 -132 K, respectively. The inspection of the M-I transition using the XANES data of Pr

Sintered, textured and single crystal products of the layered misfit [Bi 0.81 CaO 2 ] 2 [CoO 2 ] 1.69 cobaltite have been successfully synthesized and characterized. Based on structure and texture models, the orientation distribution of the hot-forged sample was successfully analysed by neutron diffraction. The results gave a clear description of the fiber texture with c-axes of the plate-like grains aligned parallel to the hot-forging direction. In terms of transport properties, the decrease of the electrical resistivity according to the degree of alignment and crystallinity of the materials evidenced the important role of the texturation and the strong anisotropy existing in these misfit layered cobaltites.

Data-Driven Review of Thermoelectric Materials: Performance and Resource Considerations

et al. 2013

View full text Add to dashboard Cite

In this review, we describe the creation of a large database of thermoelectric materials prepared by abstracting information from over 100 publications. The database has over 18 000 data points from multiple classes of compounds, whose relevant properties have been measured at several temperatures. Appropriate visualization of the data immediately allows certain insights to be gained with regard to the property space of plausible thermoelectric materials. Of particular note is that any candidate material needs to display an electrical resistivity value that is close to 1 mW cm at 300 K, i.e., samples should be significantly more conductive than the Mott minimum metallic conductivity. The Herfindahl-Hirschman index, a commonly accepted measure of market concentration, has been calculated from geological data (known elemental reserves) and geopolitical data (elemental production) for much of the periodic table. The visualization strategy employed here allows rapid sorting of thermoelectric compositions with respect to important issues of elemental scarcity and supply risk.
