| 英文摘要 | Abstract we report on anisotropic electrical, thermal as well as thermoelectric properties of the prototypical weyl semimetal taas. compared to the normal metallic behavior along a axis, taas is more electrically resistive along c axis and exhibits a semiconductor-like resistivity upturn below t≈25 k. in the same temperature range, the thermal conductivity along c axis shows a pronounced maximum of 183 wkm?1 characteristic of a crystalline solid, three times higher than that of a axis. the thermoelectric power, while exhibiting enhanced values around room temperature, becomes diminished in a substantial range of temperature (t<50 k) for both axes. together with the enhanced nernst signals, this hints at a dominating ambipolar diffusion as is frequently seen in a compensated semimetal. an in-depth investigation of the anisotropic transport quantities is expected to yield deep insights into the propagating weyl fermions in taas. |
