WebDeveloping a non-toxic tellurium-free alternative for PbTe is crucial for large-scale waste heat recovery. Here we demonstrate that a simple Cu3SbSe4–CuAlS2composite can reach a peak zTof 1.8 and an average zTof 0.77 in the temperature range of 300–723 K, both of which are the record-high values in diamond-like semiconductors. WebThese abundant, efficient, and non-toxic thermoelectric materials have been the focus of recent research by the thermoelectric community, as ... (along with tennantite, Cu 12 As 4 S 13, which crystallize into an isomorphous cubic structure) have a rather high thermoelectric performance. Although tetrahedrites have been known as minerals for ...

High thermoelectric performance in copper telluride

WebApr 1, 2024 · The work provides an excellent reference to develop non-toxic high-performance TE materials. Author contributions Tao Hong conceived and carried out the experiments, synthesized the samples, performed the SEM and TEM measurements with the assistance of Xiang Gao and wrote this paper. WebLow-cost, non-toxic, abundant organic thermoelectric materials are currently under investigation for use as potential alternatives for the production of electricity from waste heat. While organic conductors reach electrical conductivities as high as their inorganic counterparts, they suffer from an overall low thermoelectric figure of merit (ZT ... popham state beach maine
