The Shanghai Institute of Ceramics has achieved breakthrough progress in the research of bismuth telluride-based plastic thermoelectric materials.

Bismuth telluride (Bi2Te3)-based thermoelectric materials encompass Bi2Te3 itself as well as its pseudo-binary solid solutions formed with Bi2Se3 and Sb2Te3. These materials have already achieved widespread commercial applications in areas such as solid-state refrigeration, precise temperature control, and localized thermal management. However, Bi2Te3-based materials are inherently brittle and prone to cleavage fracture under external mechanical stress, severely limiting their application in fields like flexible/microelectronics.

The Shanghai Institute of Ceramics has published an important advance in semiconductor plastic processing in Nature Materials.

Semiconductor materials, with their rich and tunable functional properties, are widely used; however, at room temperature, they typically exhibit brittleness, making it difficult to perform simple and efficient plastic deformation as is possible with metals. Instead, they rely extensively on a series of highly sophisticated preparation and precision machining techniques, which are costly and involve complex process flows.

The Shanghai Institute of Ceramics publishes progress in the plasticization and regulation research of inorganic non-metallic materials.

Researchers Qiu Pengfei, Shi Xun, and Chen Lidong from the Shanghai Institute of Ceramics, Chinese Academy of Sciences, along with their collaborators, have achieved a transformation of brittle bismuth telluride (Bi2Te3)-based materials from brittle to ductile by modulating anti-site defects to induce the formation of high-density and diversified microstructures. This breakthrough has boosted the room-temperature thermoelectric figure of merit of ductile thermoelectric materials to approximately 1.0. The relevant findings were recently published in "Science."

The Shanghai Institute of Ceramics has made significant progress in the study of critical thermoelectric performance.

The combination of the thermoelectric effect and critical phenomena has given rise to the field of critical electrothermal transport research. However, current understanding of its underlying physical mechanisms mostly remains at a qualitative level, or focuses only on quantitative physical models for either resistivity or the Seebeck coefficient alone. Therefore, a deeper understanding and characterization of critical electrothermal transport phenomena, along with the development of a universal model that encompasses all aspects of electrical transport, would hold significant theoretical importance and practical value for the study of critical thermoelectric effects.
