Thermoelectric Materials: Principles, Structure, Properties, and Applications
During the 1990s there was a heightened interest in the field of thermoelectrics driven by the need for more efficient materials for electronic refrigeration and power generation (Nolas et al. 2002, Tritt et al. 2000a, Tritt et al. 1998, Tritt et al. 1997). Proposed industrial and military applications of thermoelectric (TE) materials are generating increased activity in this field by demanding...
متن کاملModeling the Thermoelectric Properties of Bulk and Nanocomposite Thermoelectric Materials
Thermoelectric materials are materials which are capable of converting heat directly into electricity. They have long been used in specialized fields where high reliability is needed, such as space power generation. Recently, certain nanostructured materials have been fabricated with high thermoelectric properties than those of commercial bulk materials, leading to a renewed interest in thermoe...
متن کاملChalcopyrite Nanoparticles as a Sustainable Thermoelectric Material
In this report, copper iron sulfide nanoparticles with various composition were synthesized by a thermolysis based wet chemical method. These inherently sustainable nanoparticles were then fully characterized in terms of composition, structure, and morphology, as well as for suitability as a thermoelectric material. The merits of the material preparation include a straightforward bulk material ...
متن کاملMeasuring thermoelectric transport properties of materials
In this review we discuss considerations regarding the common techniques used for measuring thermoelectric transport properties necessary for calculating the thermoelectric figure of merit, zT. Advice for improving the data quality in Seebeck coefficient, electrical resistivity, and thermal conductivity (from flash diffusivity and heat capacity) measurements are given together with methods for ...
متن کاملEnhanced thermoelectric performance of a chalcopyrite compound CuIn3Se5−xTex (x = 0~0.5) through crystal structure engineering
In this work the chalcopyrite CuIn3Se5-xTex (x = 0~0.5) with space group through isoelectronic substitution of Te for Se have been prepared, and the crystal structure dilation has been observed with increasing Te content. This substitution allows the anion position displacement ∆u = 0.25-u to be zero at x ≈ 0.15. However, the material at x = 0.1 (∆u = 0.15 × 10-3), which is the critical Te cont...
