| 1 | On the tuning of electrical and thermal transport in thermoelectrics: an integrated theory–experiment perspective显示文摘During the last two decades,we have witnessed great progress in research on thermoelectrics.There are two primary focuses.One is the fundamental understanding of electrical and thermal transport,enabled by the interplay of theory and experiment;the other is the substantial enhancement of the performance of various thermoelectric materials,through synergistic optimisation of those intercorrelated transport parameters.Here we review some of the successful strategies for tuning electrical and thermal transport.For electrical transport,we start from the classical but still very active strategy of tuning band degeneracy(or band convergence),then discuss the engineering of carrier scattering,and finally address the concept of conduction channels and conductive networks that emerge in complex thermoelectric materials.For thermal transport,we summarise the approaches for studying thermal transport based on phonon–phonon interactions valid for conventional solids,as well as some quantitative efforts for nanostructures.We also discuss the thermal transport in complex materials with chemical-bond hierarchy,in which a portion of the atoms(or subunits)are weakly bonded to the rest of the structure,leading to an intrinsic manifestation of part-crystalline part-liquid state at elevated temperatures.In this review,we provide a summary of achievements made in recent studies of thermoelectric transport properties,and demonstrate how they have led to improvements in thermoelectric performance by the integration of modern theory and experiment,and point out some challenges and possible directions. | Jiong Yang Lili Xi Wujie Qiu Lihua Wu Xun Shi Lidong Chen Jihui Yang Wenqing Zhang Ctirad Uher David J Singh | 2016 | npj Computational Materials2016，，1： | 24 |
| 2 | Grain boundary engineering with nano-scale InSb producing high performance In_(x)Ce_(y)Co_(4)Sb_(12+z)skutterudite thermoelectrics显示文摘Thermoelectric semiconductors based on CoSb_(3)hold the best promise for recovering industrial or automotive waste heat because of their high efficiency and relatively abundant,lead-free constituent elements.However,higher efficiency is needed before thermoelectrics reach economic viability for widespread use.In this study,n-type In_(x)Ce_(y)Co_(4)Sb_(12+z)skutterudites with high thermoelectric performance are produced by combining several phonon scattering mechanisms in a panoscopic synthesis.Using melt spinning followed by spark plasma sintering(MS-SPS),bulk In_(x)Ce_(y)Co_(4)Sb_(12+z)alloys are formed with grain boundaries decorated with nano-phase of InSb.The skutterudite matrix has grains on a scale of 100-200 nm and the InSb nano-phase with a typical size of 5e15 nm is evenly dispersed at the grain boundaries of the skutterudite matrix.Coupled with the presence of defects on the Sb sublattice,this multi-scale nanometer structure is exceptionally effective in scattering phonons and,therefore,InxCey-Co_(4)Sb_(12)/InSb nano-composites have very low lattice thermal conductivity and high zT values reaching in excess of 1.5 at 800 K. | Han Li Xianli Su Xinfeng Tang Qingjie Zhang Ctirad Uher G.Jeffrey Snyder Umut Aydemir | 2017 | Journal of Materiomics2017，3，4： | 7 |
| 3 | Eco-friendly high-performance silicide thermoelectric materials显示文摘Silicide-based thermoelectrics are examples of cost-efficient and environmentally friendly new energy materials, which can be used for power-generation applications in the range of 500–800 K. We review the research focusing on the exploration of n-type Mg_2IV-based solid solutions(IV = Si, Ge and Sn) and summarize the most prominent discoveries achieved so far in their studies. Owing to their superior performance compared to other silicides, including p-type Mg_2IV, higher manganese silicides(HMS) are commonly considered as a suitable p-type material to be used in thermoelectric modules in conjunction with n-type Mg_2IV-based solid solutions for mid-temperature power-generation applications. We describe the strategies used to improve the thermal and electronic transport properties of n-type Mg_2IV-based solid solutions and mention some key features of HMS. We also point out the importance of mechanical properties and thermal stability of this family of materials and offer perspectives on the future research work to further improve their performance. | Wei Liu Kang Yin Qingjie Zhang Ctirad Uher Xinfeng Tang | 2017 | National Science Review2017，4，4： | 5 |
| 4 | Rapid fabrication and thermoelectric performance of SnTe via non-equilibrium laser 3D printing显示文摘Thermoelectric technologies based on Seebeck and Peltier effects,as energy techniques able to directly convert heat into electricity and vice versa, hold promise for addressing the global energy and environmental problems. The development of efficient and low-cost thermoelectric modules is the key to their large-scale commercial applications. In this paper, using a non-equilibrium laser3 D printing technique, we focus an attention on the fabrication of mid-temperature p-type SnTe thermoelectric materials. The influence of laser power, scanning speed and layer thickness on the macro-defects, chemical and phase composition, micro structure and thermoelectric performance was systematically investigated. First and foremost,the processing parameter window for printing a highquality layer is determined. This is followed by the finite element method used to simulate and verify the influence of the laser-induced molten pool temperature distribution on the final composition and microstructure. Finally, the high-performance SnTe layer with 10 mm × 10 mm in area is produced within seconds with room temperature Seebeck coefficient close to that of SnTe manufactured by the traditional methods. Consequently,this work lays a solid foundation for the future fabrication of thermoelectric modules using laser non-equilibrium printing techniques. | Tian-Le Chen Chuang Luo Yong-Gao Yan Ji-Hui Yang Qing-Jie Zhang Ctirad Uher Xin-Feng Tang | 2018 | Rare Metals2018，37，4： | 3 |
| 5 | 通过增强织构和诱导高密度线缺陷获得优异性能的Bi_(0.4)Sb_(1.6)Te_(3.72)热电材料显示文摘商业化的区熔(ZM)Bi_(2)Te_(3)基单晶锭体力学性能差、热电转换效率不足,一直阻碍着高效热电器件的微型化.本文将超快速热爆反应与放电等离子体烧结技术相结合,成功制备出了高强度、高热电性能的Bi_(0.4)Sb_(1.6)Te_(3.72)块体合金.我们观察到,引入过量Te不仅增强了(00l)织构,使得材料室温功率因子高达5 mW m−1 K−2,而且还诱导了密度高达10^(11)–10^(12)cm^(−2)的线缺陷.与电子热导率的增加幅度相比,如此高浓度的线缺陷使得晶格热导率下降的幅度更大,致使总热导明显降低.最终,Bi_(0.4)Sb_(1.6)Te_(3.72)材料在350 K下最大ZT值可达1.4,比商业ZM锭体高出40%.此外,这种高密度的线缺陷还提升了材料的机械抗压强度,其最大抗压强度为94 MPa,比ZM单晶高出154%.本文为Bi_(2)Te_(3)基热电材料的织构、热电性能及力学性能的协同优化提供了一种简单有效的策略,也为微型化热电器件的商业化开发奠定了重要基础. | 邱俊豪 鄢永高 谢鸿耀 罗婷婷 夏凡杰 姚磊 张敏 祝婷 谭刚健 苏贤礼 吴劲松 Ctirad Uher 姜洪义 唐新峰 | 2021 | Science China Materials2021，64，6： | 2 |

| 9 | A comprehensive review on Bi_(2)Te_(3)-based thin films: Thermoelectrics and beyond显示文摘Bi_(2)Te_(3)-based materials are not only the most important and widely used room temperature thermoelectric(TE)materials but are also canonical examples of topological insulators in which the topological surface states are protected by the time-reversal symmetry.High-performance thin films based on Bi_(2)Te_(3)- have attracted worldwide attention during the past two decades due primarily to their outstanding TE performance as highly efficient TE coolers and as miniature and flexible TE power generators for a variety of electronic devices.Moreover,intriguing topological phenomena,such as the quantum anomalous Hall effect and topological superconductivity discovered in Bi_(2)Te_(3)-based thin films and heterostructures,have shaped research directions in the field of condensed matter physics.In Bi_(2)Te_(3)-based films and heterostructures,delicate control of the carrier transport,film composition,and microstructure are prerequisites for successful device operations as well as for experimental verification of exotic topological phenomena.This review summarizes the recent progress made in atomic defect engineering,carrier tuning,and band engineering down to a nanoscale regime and how it relates to the growth and fabrication of high-quality Bi_(2)Te_(3)-based films.The review also briefly discusses the physical insight into the exciting field of topological phenomena that were so dramatically realized in Bi_(2)Te_(3)-and Bi_(2)Se_(3)‐based structures.It is expected that Bi_(2)Te_(3)-based thin films and heterostructures will play an ever more prominent role as flexible TE devices collecting and converting low-level(body)heat into electricity for numerous electronic applications.It is also likely that such films will continue to be a remarkable platform for the realization of novel topological phenomena. | Xinfeng Tang Ziwei Li Wei Liu ingjie Zhang Ctirad Uher | 2022 | Interdisciplinary Materials2022，1，1： | 1 |
