Hanoi, March 19, 2026 – The Center for Materials Innovation & Technology (CMIT) at VinUniversity organized a seminar featuring Prof. Philippe Lecoeur from Paris-Saclay University. The session examined fundamental and practical aspects of modeling and characterizing thermoelectric materials and devices.

In his talk, Prof. Lecoeur outlined the unique interplay between heat and charge transport in thermoelectric systems and their potential for energy conversion technologies. He emphasized key barriers to broader application, including limited efficiency and the lack of robust measurement approaches for accurately assessing transport properties and coupling behavior across different operating conditions. 

The seminar also highlighted nonlinear impedance spectroscopy as a powerful characterization technique. This method enables the simultaneous evaluation of intrinsic material properties and external coupling effects within a unified experimental framework, offering new insights into optimizing thermoelectric performance.

Prof. Lecoeur is a Full Professor at Paris-Saclay University, where his research focuses on functional oxide materials for applications in micro- and nanoelectronics. His work includes the study of epitaxial thin films, such as magnetic, ferroelectric, and thermoelectric oxides, and their integration with semiconductor technologies. Presently, he serves as a Vice Dean for Research at Universite Paris Saclay. He previously held academic positions at the University of Caen and completed postdoctoral research at the IBM Yorktown Heights Research Center.
