Weak Host Interactions Induced Thermal Transport Properties of Metal Halide Perovskites Deviating from the Rattling Model
Yu Wu, Linxuan Ji, Shuming Zeng +2
The low-frequency phonon branches of metal halide perovskites typically exhibit the characteristic of hardening with the increase of the cation mass, which leads to anomalous therm…

When is the Four-phonon Effect in Half-Heusler Materials more Pronounced?
Yu Wu, Shengnan Dai, Linxuan Ji +3
Suppressed three-phonon scattering processes have been considered to be the direct cause of materials exhibiting significant higher-order four-phonon interactions. However, after c…
