Abstract |
The NanoHiTEC project is focused on planar thermo-electric converters based on super-lattice quantum wells, which have shown on laboratory scale already a figure of merit ZT > 4 for a wide temperature range. The optimization of BiTe based layer systems as well as Si/SiGe and B4C/B9C lattices will be combined with the development of low cost/high throughput industrial deposition processes for multilayers. Direct p-n-junctions at the hot side of the converter promise further increase in performance and long term stability of the devices, but also simplified fabrication. As technologies for improved material performance multilayered nanowires and sintered nanopowders will be investigated. |
Kurzfassung |
Das Projekt NanoHiTEC behandelt planare thermoelektrische Konverter, welche auf so genannten Übergittern basieren. Mit diesen Systemen konnte unter Laborbedingungen bereits eine Gütezahl ZT > 4 über einem weiten Temperaturbereich erreicht werden. BiTe-Schichtsysteme sowie Si/SiGe- und B4C/B9C-Übergitter sollen für kostengünstige industrielle Abscheidungsprozesse mit hohem Durchsatz optimiert werden. |
