Mg<sub>3</sub>Sb<sub>2</sub> based Zintl compounds are promising thermoelectric materials due to the abundance of magnesium and antimony in nature.
Thermoelectric textiles, constructed from thermoelectric materials and fabric, offer unique advantages compared to other types as they facilitate thermal energy harvesting the human body conform exceptionally well dynamic curves. This underscores their potential for on-body applications in electricity generation. In this investigation, we present a tellurium–free polymer-based textile prototype manufactured through cost-effective method known solution drop-casting process. Two organic...
We report the evolution of thermoelectric and mechanical properties n-type SnSe obtained by iodine doping at Se site.
Polymer thermoelectics are an emerging class of materials for realizing flexible thermoelectric devices due to its low cost, solution processability and bio-compatibility. We report a systematic investigation the charge transport properties polymer composites comprising tellurium (Te) nanorods poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) spanning over temperature range from 10 K up 320 K. The dependence electrical resistivity Te:(PEDOT:PSS) is dominated by thermal...
In the present work, we report on investigation of low-temperature (300-5 K) thermoelectric properties hot-pressed TiSe2, a charge-density-wave (CDW) material. We demonstrate that, with increasing hot-pressing temperature, density TiSe2 increases and becomes nonstoichiometric owing to loss selenium. X-ray diffraction, scanning electron microscopy, transimission microscopy results show that material consists layered microstructure several defects. Increasing hot-press temperature in leads...
In this paper we report the thermoelectric performance of Sr intercalated TiSe(2) above 300 K. Refined x-ray diffraction, high resolution transmission electron microscopy and scanning images show well oriented polycrystalline grains along a (0 0 l) direction layered growth sample. Intercalation in shows an improved Seebeck coefficient (α) value without altering polarity majority charge carrier. A drastic reduction thermal conductivity (κ) from 3.8 W m K(-1) to 1.2 (at 650 K) was observed...
We report a systematic investigation of the microstructure and thermoelectric properties refractory element-filled nanostructured Co4Sb12 skutterudites. The tantalum (Ta) metal-filled samples (TaxCo4Sb12 (x = 0, 0.4, 0.6, 0.8)) are synthesized using solid-state synthesis route. All composed single skutterudite phase. Meanwhile, nanometer-sized equiaxed grains present in Ta0.2Co4Sb12 Ta0.4Co4Sb12 samples, bimodal distributions elongated observed Ta0.6Co4Sb12 Ta0.8Co4Sb12 samples. dominant...
