Thermoelectric technology, which can convert waste heat into electrical energy without moving parts, offers a promising solution to the critical energy and environmental challenges. However, the large-scale application of this technology is critically limited by materials being low-performing or expensive. During his studies, Jiawei Zhang devised novel strategies and guiding principles for electrical transport optimizations in layered materials. Guided by his theoretical prediction, Jiawei Zhang experimentally discovered several high-performance low-cost layered thermoelectric materials. Moreover, Jiawei Zhang unveiled how chemical bonding paves a shortcut in understanding structure and transport properties. The guiding principles he proposed lead to better understanding of structure-property relation and thereby will accelerate the screening and design of new layered thermoelectric materials.
