Specially, the Bridgman-grown eutectic alloy exhibited a partially aligned lamellar microstructure, which consisted of Ag 5Te 3 and Te phases, with additional 200-600 nm size particles of PbTe. The self-assembled interfaces altered the thermal and electronic transport properties in the bulk Ag-Pb-Te eutectic alloy. Presumably due to phonon scattering from the nanoscale microstructure, a low thermal conductivity (κ 0.3 W/mK) was achieved of the eutectic alloy, leading to a zT peak of 0.41 at 400 K. © 2012 American Institute of Physics.journal article10.1063/1.47336612-s2.0-84863925145
