Solid State Seminar: Nano structuring and additive manufacturing towards high-performance and flexible thermoelectric energy systems


Dr. Yanliang Zhang
Department of Aerospace & Mechanical Engineering
University of Notre Dame


Nano engineering and additive manufacturing methods have led to many scientific and technology breakthroughs for energy and sensor related applications. First, this talk will present fundamental study of thermal and thermoelectric transport properties in nanostructured materials fabricated using scalable nonmanufacturing methods, which have led to significant increases in thermoelectric figure of merit ZT. Second, this talk will discuss novel additive manufacturing and interface engineering methods to fabricate efficient and flexible thermoelectric devices using colloidal nanocrystals, which resulted in unprecedented high power density and ultralow cost. Third, this talk will discuss design, modeling and manufacturing of high-performance nanostructured thermoelectric generator systems for waste heat recovery applications. Finally, this talk will present a novel scanning thermal probe method to map thermal and thermoelectric properties of nanostructured materials with high spatial resolution. The above research breakthroughs are on track to create a sustainable and commercially viable technology for automotive, industrial, electronics, and personal energy harvesting and thermal management applications.
