决定材料性质的相互作用参数通常对压力敏感。因此，压力调谐提供了一种快速探索材料的相互作用参数相空间的手段，以提高发现具有改进性质的材料的速率。在这里，我们报告了一个显着的改善近藤绝缘体NdxCe 3-xPt 3Sb 4压力调谐到2 GPa时的热电性能。这一结果为在环境压力下进行合成尝试提供了目标，以复制所观察到的改善的高压行为。
The interaction parameters that determine materials properties are generally sensitive to pressure. Thus, pressure tuning provides a means to rapidly explore a material's interaction parameter phase space to increase the rate of discovery of materials with improved properties. Here we report a significant improvement in the thermoelectric properties of the Kondo insulator NdxCe3-xPt3Sb4 upon pressure tuning to 2 GPa. This result provides a target for synthetic attempts at ambient pressure to duplicate the observed improved high-pressure behavior.
