英文摘要A novel thermoelectric Cd3P2 is obtained via regulating carrier concentrations. Ultrahigh carrier mobilities over 1500 cm(2) V-1 s(-1) are observed at room temperature, which is attributed to small band effective mass and confirmed by the electronic structure calculation. Meanwhile, the intrinsically low lattice thermal conductivity below 1.0 W m(-1) K(-1)( )in the investigated temperature range is found due to the complex crystal structure and low sound velocity. Combined with high mobility and low thermal conductivity, a peak zT of 0.91 at 673 K and an excellent average zT of 0.57 over 300-673 K are obtained in Cd3P2-based compounds, which are record-high values among phosphides. This study highlights the potential of exploring high-performance novel thermoelectric materials in compounds with high carrier mobility.
