Unusually high phonon thermal conductivity in the Weyl semimetal TaP: A comparative study with TaAs
Xianyong Ding, Xin Jin, Dengfeng Li +5
In many metals, thermal transport is often dominated by electrons, although the lattice contribution can remain appreciable depending on the material. Here, through rigorous first-…
Metavalent Bonding-Induced Phonon Hardening and Giant Anharmonicity in BeO
Xuejie Li, Yuzhou Hao, Yujie Liu +6
The search for materials with intrinsically low thermal conductivity () is critical for energy applications, yet conventional descriptors often fail to capture the complex in…
Phonon-Dominated Thermal Transport and Large Violation of the Wiedemann-Franz Law in Topological Semimetal CoSi
Luyao Zhong, Xin Jin, Mingquan He +4
The Wiedemann-Franz (WF) law, relating the electronic thermal conductivity () to the electrical conductivity, is vital in numerous applications such as in the design of…
Anharmonicity-driven phonon avoided crossing and anomalous thermal transport in nodal-line semimetal ZrSiS
Xin Jin, Qingqing Zhang, Dengfeng Li +8
Understanding thermal and electrical transport in topological materials is essential for advancing their applications in quantum technologies and energy conversion. Herein, we empl…
