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 inef…
Orbital dimerization-induced first-order structural phase transition: a case study in LaNiO
Xingchen Shen, Wei Ku
First-order structural phase transition is a common phenomenon in materials that qualitatively alters their physical properties. Yet, the abrupt first-order nature is usually unexp…
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…
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…
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…
Charge-density-wave quantum critical point under pressure in 2-TaSe
Yuliia Tymoshenko, Amir-Abbas Haghighirad, Rolf Heid +13
Suppressing of an ordered state that competes with superconductivity is one route to enhance superconducting transition temperatures. Whereas the effect of suppressing magnetic sta…
