Approaching the Limit of Intrinsic Crystalline Thermal Insulation
Ruihuan Cheng, Zhiqiang Cui, Mani Jayaraman +9
Crystalline materials with ultralow thermal conductivity () are potential thermal barrier coatings or thermoelectrics, yet the discovery of ultralow- materials remains ineffi…
Strong Crystalline Thermal Insulation Induced by Extended Antibonding States
Ruihuan Cheng, Chen Wang, Niuchang Ouyang +2
Crystalline solids with extreme insulation often exhibit a plateau or even an upward-sloping tail in thermal conductivity above room temperature. Herein, we synthesized a crystalli…
Revisit Many-body Interaction Heat Current and Thermal Conductivity Calculation in Moment Tensor Potential/LAMMPS Interface
Siu Ting Tai, Chen Wang, Ruihuan Cheng +1
The definition of heat current operator for systems for non-pairwise additive interactions and its impact on related lattice thermal conductivity () via molecular dynamics s…
Positive temperature-dependent thermal conductivity induced by wavelike phonons in complex Ag-based argyrodites
Niuchang Ouyang, Dongyi Shen, Chen Wang +3
The phonon transport mechanisms and the anomalous temperature-dependent lattice thermal conductivities (kL) in Ag-based argyrodites have not been fully understood. Herein, we syste…
Pushing thermal conductivity to its lower limit in crystals with simple structures
Zezhu Zeng, Xingchen Shen, Ruihuan Cheng +7
Materials with low thermal conductivity usually have complex crystal structures. Herein we experimentally find that a simple crystal structure material AgTlI2 (I4/mcm) owns an extr…
