Phase Boundary Engineering Enables Multivalley Activation for High-Performance ZrCoSb Half-Heuslers

Abstract P-type ZrCoSb-based half-Heusler compounds are promising thermoelectric materials for high-temperature power generation because of their excellent thermal stability and mechanical robustness. However, their performance still lags behind that of state-of-the-art p-type Zr...

Engineering Hidden Ferroelectric‐Like Distortion for Ultralow Thermal Conductivity in Polar van der Waals Tetradymite

ABSTRACT Ferroelectric‐like polar structures enable diverse functionalities through coupling with charge and phonon transport. Although effective in modulating thermal conductivity, the rational design of novel polar materials with intrinsically low thermal conductivity via ferro...
