Research: Thermoelectrics
CURRENT RESEARCH
Development of sustainable materials for thermoelectrics.
GOAL
To use nanotechnology to improve the thermoelectric properties of materials, with a particular focus on readily available and sustainable materials:
- Nanostructured silicon and silicon compounds for temperatures of 600°C and above
- Nanostructured oxides for temperatures up to 600°C and above
- Molecularly composed p- and n-type metal chalcogenides (M2E3, M = Sb, Bi; E = Se, Te) and skutterudites (Co3Sb) for temperatures up to 250°C
- Nanocrystalline diamond, as its large bandgap makes it well suited for applications at temperatures above >600°C which is of particular interest as a model system
HIGHLIGHTS
- Realization of the entire process chain, from synthesis of the material to development of test demonstration models
- 2014 North Rhine-Westphalia Innovation Award for the development of thermoelectric generators made from nanostructured silicon (awarded to Dr.-Ing. Gabi Schierning)
- 2012 InnoMateria Award for the first thermoelectric generator made from nano-silicon (UDE, IUTA, SLV)
