Strong Electron-phonon Coupling and High Lattice Thermal Conductivity in Half-Heusler Thermoelectric Material The traditional half-Heusler thermoelectric materials, identified as 18-electron compounds, are characterized by the high power factor and the high lattice thermal conductivity. Interestingly, the emerging 19-electron half-Heusler compounds were also found to be the promising thermoelectrics, but with the 5-10 times lower lattice thermal conductivity.

Structural Modulation and Resonant Level Enable High Thermoelectric Performance of GeTe in Mid-low Temperature Range GeTe has recently attracted wide attentions as a promising mid-temperature thermoelectric candidate, but the poor performance severely limits its practical application. Herein, we demonstrate a significantly improved thermoelectric properties of Sb-InSe codoped GeTe by structural modulation and resonant level.
