On October 22, 2025, at 13: 00 p.m., researcher Zhao Kun-peng of Shanghai Jiao Tong University was invited to deliver an academic report entitled Order-Disorder Structure Design and Performance Control of Thermoelectric Materials. The report was presided over by Professor Qiu Wu.

Researcher Zhao Kun-peng, a researcher in the School of Materials Science and Engineering at Shanghai Jiao Tong University, has long been devoted to the design and synthesis of novel thermoelectric materials, especially in the regulation of electron and phonon transport. His research work has not only made breakthroughs in the design of order-disorder structures of thermoelectric materials, but also made important contributions to the optimization mechanism of material properties.

In the report, researcher Kun-peng Zhao deeply analyzed the influence of order-disorder structure on the performance of thermoelectric materials and proposed a new theoretical framework. He introduced the team's latest research results in the design and performance control of thermoelectric materials, including the establishment of quantitative models of critical electrical transport properties, The influence mechanism of band broadening and phonon soft modes on electric transport properties is revealed, and a new kind of phase beyond Hume-Rothery law is discovered, This phase exhibits glass-crystal duality under the combined action of the global ordered occupation of anions and the disordered occupation of cations / large atom vibrations. In addition, researcher Zhao Kun-peng shared how to regulate the structural disorder and the Fermi level through adaptive sublattices and multi-level functional primitives to realize the regulation mechanism of thermoelectric properties. Therefore, it breaks through the limitation of optimizing only at the band edge, and further improves the performance of thermoelectric materials.

The report attracted the participation of more than 20 teachers and students from NTC, ALE and other colleges, which not only provided the teachers and students present with cutting-edge academic perspectives, but also triggered deep thinking on thermoelectric materials and their performance control. Teachers and students at the meeting said that Zhao's report was rich in content and enlightening, and that he had a more comprehensive and in-depth understanding of the design and performance control of thermoelectric materials.

The series of activities of Mathematics and Science Lectures aims to provide a platform for academic exchanges and ideas, and promote scientific innovation and academic development. In the future, we look forward to more scholars sharing the latest research results on this platform to further promote cross-disciplinary cooperation and technological breakthroughs.
