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…
Accelerated Discovery of Crystalline Materials with Record Ultralow Lattice Thermal Conductivity via a Universal Descriptor
Xingchen Shen, Jiongzhi Zheng, Michael Marek Koza +9
Ultralow glass-like lattice thermal conductivity in crystalline materials is crucial for enhancing energy conversion efficiency in thermoelectrics and thermal insulators. We introd…
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…
Diffuson-Dominated Thermal Transport Crossover from Ordered to Liquid-like CuBiS:The Negligible Role of Ion Hopping
Jincheng Yue, Jiongzhi Zheng, Xingchen Shen +7
Fundamentally understanding lattice dynamics and thermal transport behavior in liquid-like, partially occupied compounds remains a long-standing challenge in condensed matter physi…
Lone Pair Induced 1D Character and Weak Cation-anion Interactions: Two Ingredients for Low Thermal Conductivity in Mixed-anion Metal Chalcohalides
Xingchen Shen, Koushik Pal, Paribesh Acharyya +10
Mixed-anion compounds, which incorporate multiple types of anions into materials, displays tailored crystal structures and physical/chemical properties, garnering immense interests…
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…
