Non-technical summary:The study of thermoelectric materials - which enable the solid-state conversion of thermal energy into electrical energy - has grown immensely in the past decade. What was once a niche research area has transformed into diverse field spanning condensed matter physics, materials science and engineering and solid-state chemistry. The complexity of the topic (fundamentally, the study of electronic and thermal transport in a broadly defined group of materials) means that it is difficult to be fluent in all aspects of the field. For this reason, researchers benefit from the annual Fall Materials Research Society (MRS) Meeting, which brings together a large number of participants with diverse expertise. The symposium "Thermoelectric Energy Conversion: Complex Materials and Novel Theoretical Methods" at the 2019 MRS Meeting in Boston, MA attracts experts in design, synthesis, characterization and modeling of complex thermoelectric materials. The three-day session includes 48 oral presentations, 18 of which are invited, and 54 poster presentations from a diverse group of presenters. This symposium provides an ideal platform for investigators from varied backgrounds to exchange recently-gained knowledge and engage in new collaborations related to thermoelectric materials, enabling progress towards the ultimate goal of efficient waste-energy recovery. Partial support by the Solid State and Materials Chemistry program in the Division of Materials Research facilitates participation of students, postdoctoral researchers and junior faculty in this symposium.Technical summary:This 2019 Fall MRS symposium highlights fundamental research in the field of thermoelectric materials by focusing on two complementary approaches for the development of new thermoelectric materials: (a) experimental studies focused on the discovery, synthesis and understanding of materials with complexity on the atomic and microstructural levels, and (b) development of novel theoretical methods to predict such materials and structures and their implementation. Part (a) emphasizes recent progress in experimental studies of materials including but not limited to: (i) novel ternary and quaternary materials from inorganic material classes such as chalcogenides, pnictides, oxides, (ii) alloys including high entropy alloys, and (iii) multiphase and multinary composites with hierarchical microstructures. As realizing high performance thermoelectric materials requires a careful balance between various transport quantities, complexity in compositions could offer a pathway to solving this problem. Part (b) highlights new approaches to material discovery and modeling, for example, by using new high-throughput strategies and a-priori predictions of electronic and thermal transport properties. Partial support by the Solid State and Materials Chemistry program in the Division of Materials Research facilitates participation of students, postdoctoral researchers and junior faculty in this symposium.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术性总结：热电材料的研究-能够将热能固态转化为电能-在过去十年中得到了极大的发展。曾经是一个利基研究领域已经转变为跨越凝聚态物理，材料科学与工程和固态化学的多元化领域。该主题的复杂性（从根本上说，是对广泛定义的材料组中的电子和热传输的研究）意味着很难精通该领域的各个方面。出于这个原因，研究人员受益于年度秋季材料研究学会（MRS）会议，该会议汇集了大量具有不同专业知识的参与者。在马萨诸塞州波士顿举行的2019年MRS会议上，研讨会“热电能量转换：复杂材料和新颖的理论方法”吸引了复杂热电材料的设计，合成，表征和建模专家。为期三天的会议包括48个口头报告，其中18个是邀请，和54个海报介绍来自不同的小组的主持人。本次研讨会为来自不同背景的研究人员提供了一个理想的平台，以交流最近获得的知识，并参与与热电材料相关的新合作，从而实现有效废物能源回收的最终目标。材料研究部固态与材料化学项目的部分支持促进了学生、博士后研究人员和初级教师参与本次研讨会。技术总结：本次2019秋季MRS研讨会通过关注开发新型热电材料的两种互补方法，突出了热电材料领域的基础研究：（a）实验研究，着重于发现、合成和了解原子和微观结构层面上的复杂材料，和（B）开发新的理论方法来预测这样的材料和结构及其实现。部分（a）强调了材料实验研究的最新进展，包括但不限于：（i）来自无机材料类别如硫属化物、磷属化物、氧化物的新型三元和四元材料，（ii）包括高熵合金的合金，和（iii）具有分级微观结构的多相和多元复合材料。由于实现高性能热电材料需要在各种传输量之间仔细平衡，因此组合物的复杂性可以提供解决这个问题的途径。部分（B）强调了材料发现和建模的新方法，例如，通过使用新的高通量策略和电子和热输运性质的先验预测。材料研究部的固态和材料化学项目的部分支持促进了学生、博士后研究人员和初级教师参加这次研讨会。这个奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为是值得支持的。
