Investigation of microstructure and thermoelectric properties of p‐type BiSbTe/ZnO composites

In this research work, p‐type BiSbTe/ZnO (2 wt%) nanocomposite powders were fabricated by high‐energy ball milling at different milling times, and subsequently, powders were consolidated by spark plasma sintering at 673 K temperature. The existence of nanoinclusions was confirmed by SEM ‐ EDS mapping. Vickers hardness values greatly improved due to reduction in grain size which prevents the crack propagation and dispersion strengthening...
