Title

Boosting thermoelectric efficiency by nano-engineering

AuthorsMartín-González, Marisol
Issue Date5-Sep-2019
Citation2nd Iberian Thermoelectric Workshop (2019)
AbstractNowadays, it seems to be clear for a great majority of people that energy needs to be generated, conserved, and recycled in better ways. We need to prevent as much as possible to waste it, since every joule saved means less fossil fuel burnt. Because of that harvesting waste energy are becoming a popular among the scientific community. And, one of the most promising approaches is nano-engineering thermoelectric materials to produce devices. Thermoelectrics are a class of materials able to convert wasted heat energy into electricity. By controlling nano-structuration properly, their efficiency increase. And, since the devices have no moving parts, they are extremely reliable. In this talk, different approaches to nanostructure different materials will be shown and how those approaches help to increase the final efficiency of the material and the final device. I will show three recent examples: selenides of Ag and Cu done with our recent development Pulsed Hybrid Reactive Magnetron Sputtering (PHRMS),1,2 large area antidote SiGe nanomeshes,3 and a three-dimensional interconnected Bi2Te3 nanowires array.4,5
