Abstract

Energy consumption in our society is increasing rapidly. A significant fraction of the energy is lost in the form of heat. In this talk we introduce thermoelectric devices that allow direct conversion of heat into electricity. Novel metal-semiconductor nanocomposites are developed where the heat and charge transport are modified at the atomic level. Theory and experiment are compared for embedded ErAs nanoparticles in InGaAlAs semiconductor matrix as well as for ScN/ZrHfN metal semiconductor multilayers. Potential to increase the energy conversion efficiency and bring the cost down to $0.1-0.2/W will be discussed.
