论文摘要
我们报告了Marcasite结构型PTSB $ _ {1.4} $ sn $ _ {0.6} $的热电功率因数（$ s^2σ$）中的巨型各向异性。 PTSB $ _ {1.4} $ sn $ _ {0.6} $，使用环境压力通量增长方法在同一个原子网站上混合和sn时合成，与PTSB $ _2 $ _2 $和PTSN $ _2 $都不同的是一个新阶段分别单位细胞对称性。 $ s^2σ$的巨大差异沿正骨单位电池的不同主要方向应用的热流量大多是来自各向异性的Seebeck系数。
We report giant anisotropy in thermoelectric power factor ($S^2σ$) of marcasite structure-type PtSb$_{1.4}$Sn$_{0.6}$. PtSb$_{1.4}$Sn$_{0.6}$, synthesized using ambient pressure flux growth method upon mixing Sb and Sn on the same atomic site, is a new phase different from both PtSb$_2$ and PtSn$_2$ that crystallize in the cubic $Pa\bar{3}$ pyrite and $Fm\bar{3}m$ fluorite unit cell symmetry, respectively. Giant difference in $S^2σ$ for heat flow applied along different principal directions of the orthorhombic unit cell mostly stems from anisotropic Seebeck coefficients.
