Here we exhibit low cost polycrystalline antimonides for far more efficient thermoelectric waste-heat recovery within 600 K than common tellurides. This is often enabled by a style and design of Ni/Fe/Mg3SbBi and Ni/Sb/CdSb contacts for equally a prevention of chemical diffusion along with a minimal interfacial resistivity, recognizing a document https://hydrocarbonheatpumps57789.blogs100.com/31382576/the-5-second-trick-for-hydrocarbon-heat-pumps
