摘要Ga doped In2O3-based thermoelectric materials were prepared by spark plasma sintering (SPS) using sintered powders in the low temperature solid phase. The solubility of Ga in In2O3 is about 10 at%, much larger than other elements such as Ge, Ce, etc. The larger solubility of Ga allows us to optimize the thermal and electrical transport properties of Ga doped In2O3 in a wider window. While tuning the concentration of dopants, the thermoelectric performance of Ga doped In2O3 was enhanced through a synergistic approach combining band-gap engineering and phonon suppression. The power factor increases from similar to 0.5 x 10(-4) to similar to 9.6 x 10(-4) W mK(-2) at 700 degrees C while thermal conductivity reduces from similar to 4 to similar to 2 W mK(-1) at 700 degrees C in In1.9Ga0.1O3. The maximum ZT of 0.37, increased by a factor of 4 from the pristine In2O3, is achieved in In1.9Ga0.1O3 at 700 degrees C.
