Intensive Widmannstatten Nanoprecipitates Catalyze SnTe With State-of-the-Art Thermoelectric Performance.

ABSTRACT: Nanoprecipitates play a vital role in designing high-performance thermoelectric materials, particularly for those with short phonon mean-free paths. However, their effectiveness in reducing lattice thermal conductivity is hindered by the uncontrollable intensity, poor interfacial coherence, and suboptimal morphology. To address these limitations, AgPbSbTe₃ is used to alloy SnTe to form intensive Ag₂Te Widmannstätten nanoprecipitates for obtaining state-of-the-art thermoelectric performance. Advanced microscopy characterizations reveal the crystallographic orientation relationships between SnTe and Ag₂Te to guide the lath-shaped morphology of Ag₂Te, leading to the formation of the high-intensity Widmannstätten nanoprecipitates, which effectively s
