	1	Solute manipulation enabled band and defect engineering for thermoelectric enhancements of SnTe显示文摘With years of development, SnTe as a homologue of PbTe has shown great potentialfor thermoelectric applications in p-type conduction, and the most successfulstrategy is typified by alloying for maximizing the valence band degeneracy.Among the known alloy agents, MnTe has been found to be one of the most effectiveenabling a band convergence for an enhancement in electronic performance ofSnTe, yet its solubility of only ~15 at% unfortunately prevents a full optimizationin the valence band structure. This work reveals that additional PbTe alloying notonly promotes the MnTe solubility to locate the optimal valence band structure butalso increases the overall substitutional defects in the material for a substantialreduction in lattice thermal conductivity. In addition, PbTe alloying simultaneouslyoptimizes the carrier concentration due to the cation size effect. These features allenabled by such a solute manipulation synergistically lead to a very high thermoelectricfigure of merit, zT of ~1.5 in SnTe with a 20 at% MnTe and a 30 at% PbTealloying (Sn0.5Mn0.2Pb0.3Te), demonstrating the effectiveness of solute manipulationfor advancing SnTe and similar thermoelectrics.
