Cooperative Suppression Strategy for Dual Thermal Transport Channels in Crystalline Materials
Yu Wu, Ying Chen, Shuming Zeng +4
We propose a novel design principle for achieving ultralow thermal conductivity in crystalline materials via a "heavy-light and soft-stiff" structural motif. By combining heavy and…

Decoupled anisotropic Charge-Phonon Transport Enables Exceptional n-Type Thermoelectric Performance in CuBiSCl
Yu Wu, Ying Chen, Shuming Zeng +2
First-principles calculations demonstrate an exceptional decoupling of charge and thermal transport along the \textit{a}-axis in CuBiSCl. The material achieves superior electro…

Third-order Orbital Corner State and its Realization in Acoustic Crystals
Jiyu Wang, Ying Chen, Xiancong Lu
Three dimensional (3D) third-order topological insulators (TIs) have zero-dimensional (0D) corner states, which are three dimensions lower than bulk. Here we investigate the third-…
