Pr_3-xTe₄: Boost in ZT from Spike at the Fermi Level, but Not before a Good Synthesis

In this issue of Joule, Cheikh et al. show that the praseodymium telluride compound Pr_3-xTe₄ stands out as an excellent high-performance thermoelectric material. They demonstrate favorable electronic structure, which features high f electron density in orbitals with high density of states near the Fermi level that leads to power factor enhancement. These properties are brought out of the material by a successful synthesis of pure stoichiometrically controlled samples.
