论文摘要
Ca $ _ {10} $ GDCDSB $ _9 $是一个新的Zintl相，具有较大的单位电池量（〜2500Å3）和非常复杂的，无序的结构，可以推动该材料中超速导热率的实现。用于单晶的CA $ _ {10} $ gdcdsb $ _9 $接近350 $μ$ v/k，在600 k时。实验确定的电阻ca $ _ {10} $ _9 $ gdcdsb $ _9 $很低，可以使一个奇妙的因子for pff， $ $ $ w/cmm.k $^2 $在460 k处。该材料中的非凡PF值高于同一温度范围内已知的最先进材料的PF值，这表明CA $ _ {10} $ _ {10} $ recdsb $ _9 $ _9 $材料系统（RE = RARE ERACE METAL）可以用作可用来的开场性的开发效果的新功能效率的效果，以培养新的有效的效果。
Ca$_{10}$GdCdSb$_9$ is a new Zintl phase with a large unit cell volume (~2500 Å3) and a very complex, disordered structure, which can drive the realization of ultralow thermal conductivity in this material. The measured Seebeck coefficient, $α$, for single-crystalline Ca$_{10}$GdCdSb$_9$ approaches 350 $μ$V/K at 600 K. The experimentally determined electrical resistivity of Ca$_{10}$GdCdSb$_9$ is very low, leading to a remarkably high-power factor PF of 23.2 $μ$W/cm.K$^2$ at 460 K. The extraordinary PF value in this material, higher than those of the currently known state-of-the-art materials within the same temperature range, suggests that the Ca$_{10}$RECdSb$_9$ material system (RE = rare earth metal) could serve as a viable playground to harnessing new efficient thermoelectric generators.
