Insights into Low Thermal Conductivity in Inorganic Materials for Thermoelectrics

Tanmoy Ghosh et al.

Summary: Efficient manipulation of thermal conductivity and understanding of microscopic mechanisms of phonon scattering are crucial for achieving high thermoelectric performance. Various strategies including nanostructural modifications, introduction of phonon scattering centers, and manipulation of defects and disorder have been developed to lower thermal conductivity in crystalline solids. Intrinsic lattice distortion and lattice anharmonicity originating from mechanisms such as rattling and bonding heterogeneity have recently gained popularity. This Perspective outlines the role of chemical bonding and structural chemistry in controlling thermal transport in high-performance thermoelectric materials.

High-Throughput Screening of Rattling-Induced Ultralow Lattice Thermal Conductivity in Semiconductors

Jielan Li et al.

Summary: In this study, we propose an efficient method to screen candidates with ultralow thermal conductivity in materials by analyzing the key spirit of the rattling model. Using a combination of structural information extraction and high-throughput computation, we identify 532 materials with ultralow thermal conductivity and verify the ultralow thermal conductivity of halide double perovskite structures.

High-entropy Sm2B2O7 (B=Ti, Zr, Sn, Hf, Y, Yb, Nb, and Ta) oxides with highly disordered B-site cations for ultralow thermal conductivity

Liang Xu et al.

Summary: A family of high-entropy Sm2B2O7 oxides with highly disordered cations on the B-site, synthesized by introducing atomic-size mismatch, mass and charge disorder, were investigated. By tuning the composition, the oxides transformed from pyrochlore to fluorite structure, accompanied with an order-disorder transition. The high-entropy fluorite Sm-2(Nb0.2Ta0.2Y0.2Yb0.2Zr0.2)(2)O-7 showed low thermal conductivity, average thermal expansion coefficient, and high-temperature stability, making it a promising candidate for thermal barrier coatings and thermally insulators.

Functional-Unit-Based Material Design: Ultralow Thermal Conductivity in Thermoelectrics with Linear Triatomic Resonant Bonds

Jialin Ji et al.

Summary: This study demonstrates the use of functional-unit-based material design for thermoelectrics. By screening compounds with linear triatomic resonant bonds (LTRBs), it is found that these compounds exhibit strong anisotropy both structurally and electronically, as well as strong anharmonic phonon scattering. Compounds containing LTRBs have lower lattice thermal conductivities and remarkable band anisotropy near the valence band maximums. The correlation between LTRB and thermoelectric properties is elucidated through a case study on K5CuSb2.

Ultralow Lattice Thermal Conductivity at Room Temperature in Cu4TiSe4

Biplab Koley et al.

Summary: Cu4TiSe4 is a unique example of a non-toxic and low-cost material with an ultra-low lattice thermal conductivity, mainly attributed to the atomic lattice and its dynamics. This material could potentially pave the way for efficient thermoelectric materials with relatively high electrical resistivity and a large band gap.

Contribution of optical phonons to lattice thermal conductivity in complex structural thermal insulation materials

Zheng Li et al.

Summary: The contribution of optical phonons in complex structural low thermal conductivity oxides, especially in La2Zr2O7, was found to be significant. As structural complexity increases, the contribution of optical phonons becomes more pronounced. This highlights the importance of considering optical phonon contributions in understanding lattice thermal conductivity in crystalline materials.
