Wave-like Tunneling of Phonons Dominates Glass-like Thermal Transport in Quasi-1D Copper Halide CsCu2I3
Jiongzhi Zheng, Changpeng Lin, Chongjia Lin +3
Fundamental understanding of thermal transport in compounds with ultra-low thermal conductivity remains challenging, primarily due to the limitations of conventional lattice dynami…
Anomalous Thermal Transport of SrTiO Driven by Anharmonic Phonon Renormalization
Jian Han, Changpeng Lin, Ce-wen Nan +2
SrTiO has been extensively investigated owing to its abundant degrees of freedom for modulation. However, the microscopic mechanism of thermal transport especially the relation…
Unravelling Ultralow Thermal Conductivity in Double Perovskite Cs2AgBiBr6: Dominant Wave-like Phonon Tunnelling, Strong Quartic Anharmonicity and Lattice Instability
Jiongzhi Zheng, Changpeng Lin, Chongjia Lin +3
In this work, we investigate the microscopic mechanisms of anharmonic lattice dynamics and thermal transport in lead-free halide double perovskite Cs2AgBiBr6 from first principles.…
General invariance and equilibrium conditions for lattice dynamics in 1D, 2D, and 3D materials
Changpeng Lin, Samuel Poncé, Nicola Marzari
The long-wavelength behavior of vibrational modes plays a central role in carrier transport, phonon-assisted optical properties, superconductivity, and thermomechanical and thermoe…
