Highly Converged Valence Bands and Ultralow Lattice Thermal Conductivity for High-Performance SnTe Thermoelectrics.A two-step optimization strategy is used to improve the thermoelectric performance of SnTe via modulating the electronic structure and phonon transport.  The lattice thermal conductivity of Sn0.83 Ag0.03 Mn0.17 Te reached to an ultralow value (ca. 0.3 W m-1  K-1 ) at 865 K, owing to the formation of Ag7 Te4 nanoprecipitates in SnTe matrix.  A high thermoelectric figure of merit (z T≈1.45 at 865 K) was obtained in Sn0.83 Ag0.03 Mn0.17 Te.
