The ever-increasing energy demand in human life emphasizes the need of clean and renewable energy resources, and the decrease of energy dispassion as much as possible. Thermoelectricity and superconductivity are two representative physical phenomena promising for these energy-related applications. The former converts waste heat into clean electric power and the latter enables dispassion-less electric transport. When joining a thermoelectric and a superconductor together, the conceptually even more appealing superconductor thermo-generator, which can transfer heat into power without resistive losses, can be expected. Considering these broad applications, there has been a resurgence in the search for new class of materials to design high efficiency energy conversion systems. In this talk, Dr. Usman will focus on recent advances in the above-mentioned cutting-edge concepts towards practical applications.
