Here we demonstrate low-priced polycrystalline antimonides for more productive thermoelectric waste-heat recovery inside 600 K than common tellurides. This is certainly enabled by a layout of Ni/Fe/Mg3SbBi and Ni/Sb/CdSb contacts for the two a avoidance of chemical diffusion as well as a low interfacial resistivity, noticing a document and secure https://devinqiwmg.livebloggs.com/37439712/not-known-facts-about-waste-heat-recovery
