This article investigates the role of metavalent bonding in improving the thermoelectric performance of elemental tellurium (Te). The study reveals that doping Te with elements such as As, Sb, and Bi leads to the formation of metavalently bonded telluride precipitates, which significantly enhance the electrical conductivity and power factor of Te. These precipitates form beneficial interfaces with the Te matrix, contributing to the overall thermoelectric performance. The research also highlights the importance of understanding the local structure-property relationships in Te-based thermoelectrics, as traditional doping methods may not fully account for the complex interactions between the matrix and precipitates. The study uses a combination of experimental techniques, including atom probe tomography (APT), scanning electron microscopy (SEM), and density functional theory (DFT) calculations, to analyze the microstructure and bonding characteristics of Te doped with various elements. The results show that metavalent bonding in telluride precipitates leads to unique electronic and thermal properties, which are crucial for enhancing the thermoelectric performance of Te. The research also provides a quantum-mechanical-based map for predicting potential dopants for Te thermoelectrics, identifying compounds such as GeTe and SnTe as promising candidates due to their metavalent bonding characteristics. The findings demonstrate that metavalent bonding in telluride precipitates plays a key role in improving the thermoelectric performance of Te, offering new insights into the design of high-performance thermoelectric materials. The study underscores the importance of considering both the local structure and the interface properties in the development of efficient thermoelectric composites. The results also highlight the potential of combining different theoretical approaches, such as spin theory, topological insulator theory, and metavalent bonding theory, to further advance the understanding and design of thermoelectric materials.This article investigates the role of metavalent bonding in improving the thermoelectric performance of elemental tellurium (Te).
