Final Activity Report Summary - NANO-THERMOELECTRICS (Thermal and Thermoelectric Transport in Nanomaterials)
The project goal was to develop new nanostructured thermoelectric materials of unprecedented efficiency for thermoelectric energy conversion applications, such as cooling and power generation. The main scientific achievements of the project were the following: 1. the invention of a new class of thermoelectric nanocomposites consisting of silicide nanoparticles in SiGe matrix, which were considerably superior to standard SiGe. 2. the development of the first ab-initio based computations of thermal conductivity in nanostructured materials, with an application to isotope disordered boron nitride (BN) nanotubes. 3. the development of pioneering ab-initio calculations of thermal conductivity in bulk semiconductors without adjustable parameters. 4. the theoretical computation and experimental measurement of ultra-low thermal conductivity of carbon nanotube pellets. 5. the experimental tailoring of thermal conductivity of Ge/Si nanodot layered materials over spatially defined regions as small as 20 nm. Our experimental measurements and associated theoretical computations opened up new possibilities for the control of thermal conductivity at the nanoscale.

Project objective
This proposal aims at developing new nanostructured materials with tailored thermoelectric properties. Ultimately, this may lead to the development of thermoelectric coolers and power generators of unprecedented efficiency, as well as new materials for he at sinks in microelectronics, or for thermal insulation. To achieve this goal, a multidisciplinary effort is being set forth, linking fundamental theory and experiment, together with nanomaterials' synthesis and characterization.The present proposal focuses on the theoretical, computational and modelling aspects, and their comparison with experiment, within the larger project. This project is very relevant to the energy problems faced by the world today: thermoelectric power generation is a clean, renewable energy source, and this project may open the way to make this source into an economically viable alternative. This project is at the cutting edge of the thermoelectrics field, and involves several renowned groups worldwide in this discipline. The project coordinates efforts in all necessary aspects, from basic to be applied, in order to achieve the final goals.
