Anharmonicity Driven by Vacancy Ordering Unlocks High-performance Thermoelectric Conversion in Defective Chalcopyrites II-III-VI
Hui Zhang, Jincheng Yue, Jiongzhi Zheng +8
Defective chalcopyrites have recently emerged as promising thermoelectric materials because their ordered intrinsic vacancies can profoundly reshape both lattice dynamics and elect…
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…
Bidirectional Optimization onto Thermoelectric Performance via Hydrostatic-Pressure in Chalcopyrite AgXTe2 (X=In, Ga)
Siqi Guo, Jincheng Yue, Jiongzhi Zheng +5
Pressure tuning has emerged as a powerful strategy for manipulating the thermoelectric properties of materials by inducing structural and electronic modifications. Herein, we syste…
Efficient Cross-layer Thermal Transport with Atypical Glassy-like Phenomena in Crystalline CsCuSe
Jincheng Yue, Yanhui Liu, Jiongzhi Zheng
Understanding lattice dynamics and thermal transport in crystalline compounds with intrinsically low lattice thermal conductivity () is crucial in condensed matter physics. In…
Hierarchical Characterization of Thermoelectric Performance in Copper-Based Chalcogenide CsCuS: Unveiling the role of Anharmonic Lattice Dynamics
Jincheng Yue, Jiongzhi Zheng, Junda Li +4
We explicitly consider both phonon energy shifts and broadening arising from both cubic and quartic anharmonicities, as well as diagonal/non-diagonal terms of heat flux operators i…
Ultra-low glassy thermal conductivity and controllable, promising thermoelectric properties in crystalline o-CsCu5S3
Jincheng Yue, Jiongzhi Zheng, Junda Li +5
We thoroughly investigate the microscopic mechanisms of the thermal transport in orthorhombic \textit{o}-CsCuS by integrating the first-principles-based self-consistent pho…
