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.

Abstract Diamond like ternary chalcopyrites MBX2 (M=Cu,Ag; B=Ga,In,Tl; X=S,Se,Te) have attracted tremendous research interest in thermoelectric society due to the competitive performance and a great variety of transport properties. Interestingly, the lattice thermal conductivity of AgBX2 is systematically two to five times lower that of CuBX2, in spite of their similar crystal and band structures.
