| Abstract | We review solid-state devices that allow direct conversion of heat into electricity. We describe fundamental and practical limits of conventional thermoelectric materials. Novel metal-semiconductor nanocomposites are developed where the heat and charge transport are modified at the atomic level. Potential to reach high power densities and high conversion efficiencies will be discussed. We also describe how similar principles can be used to reduce heating in optoelectronic devices and make micro refrigerators on a chip in order to remove hot spots in integrated circuits. |
